Description

Technical Field

[0001] The invention relates to the field of grouting equipment, in particular to a repair grouting device for water conservancy construction. Background Art

[0002] Grouting technology construction mainly uses air pressure, hydraulic pressure or electrochemical principles to inject slurry with coagulation ability into the cracks, pores or strata that need to be repaired, and squeezes out the moisture and air between soil particles or rock cracks by filling, infiltration, compaction, etc. After the slurry coagulates, it forms a whole with high strength and good anti-seepage performance, thereby achieving the purpose of repair and reinforcement. It is mainly used to repair cracks, strengthen foundations, prevent seepage and plug leaks, etc. It can play a very significant effect on crack repair in water conservancy engineering buildings;

[0003] When performing grouting construction, it is necessary to drill corresponding grouting holes at the cracks according to the selected grouting method, and then clean the grouting holes. In order to allow the slurry to fill the grouting holes and penetrate into the gaps for filling, it is necessary to insert grouting nails into the grouting holes one by one after the grouting holes are cleaned and then grouting is performed. When the repair area is large, not only are more grouting holes opened, but construction workers are also required to insert the same number of grouting nails one by one. The steps are cumbersome, which greatly delays the construction time, increases the workload, and affects the entire grouting period. Summary of the invention

DETAILED DESCRIPTION

[0046] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0047] like Figure 1-16 As shown, the present invention provides a repair grouting device for water conservancy construction, comprising a housing 1, wherein a placement tube 3 capable of intermittent rotation is arranged inside the housing 1, and a plurality of placement grooves are respectively opened from the front end to the rear end of the placement tube 3, such as Figure 4 As shown, a plurality of placement grooves are radially distributed with the axis of the placement tube 3 as the center, and a plurality of grouting nails 4 are placed in each placement groove, which are evenly arranged along the radial direction of the placement tube 3. The width of the placement groove is equal to the diameter of the grouting nail 4, and the inner ends of the placement grooves are slidably connected with elastic pushing components that can move outward. A removal hole equal to the diameter of the grouting nail 4 is opened on the outer side of the rear end of the placement groove, and the removal hole is coaxially arranged with the grouting nail 4 located at the outermost side. The elastic pushing component is used to provide a thrust for the grouting nail 4 to move outward, and the removal hole is used for the grouting nail 4 to be removed and inserted into the grouting hole. Each time a grouting nail 4 is removed, the grouting nail 4 on the inner side can be pushed by the elastic pushing component to move to the outer side corresponding to the removal hole, so as to help the construction personnel to continuously remove the grouting nails 4 in the placement tube 3.

[0048] Furthermore, a pushing component capable of moving up and down is provided on the upper side of the placing cylinder 3, and a control component capable of controlling the intermittent rotation of the placing cylinder 3 and the up and down movement of the pushing component alternately is installed at the front end inside the housing 1. Under the control of the control component, each time the pushing component moves upward, the placing cylinder 3 rotates intermittently once, and then the pushing component moves downward to reset;

[0049] The pushing component includes a guiding shell 16 that is slidably connected to the housing 1 and can move up and down. A pushing cylinder 37 that can move back and forth is slidably connected inside the guiding shell 16. The pushing cylinder 37 has a hollow structure with openings at both the front and rear ends. The diameter of the pushing cylinder 37 is equal to the diameter of the grouting nail 4, and it can be connected to the grouting nail 4 while pushing the grouting nail 4. The pushing cylinder 37 is located on the front side of the placing cylinder 3. Each time the placing cylinder 3 rotates once, one of the grouting nails 4 located in the outermost placing groove corresponds to the pushing cylinder 37. The grouting nail 4 is pushed out of the placing groove through the pushing cylinder 37. When the device is in use, the removal hole is aligned with the grouting hole. By operating the control component, the grouting nails 4 inside the placing cylinder 3 can be automatically inserted into the grouting hole, saving the operation steps of construction workers inserting the grouting nails 4 into the grouting hole one by one manually, and replacing manual force with mechanical power, which not only greatly improves the construction efficiency, effectively saves manpower, and reduces the work burden of construction workers. The grouting nails 4 are respectively loaded into the placing cylinder 3, which is convenient to carry and can achieve the effect of being available for use at any time.

[0050] Furthermore, in order to facilitate construction workers to control the device to align the removal hole with the grouting hole, a base 2 capable of moving back and forth is slidably fitted at the rear end of the housing 1. The rear end of the placing cylinder 3 is rotatably connected to the middle of the base 2. A tubular plug 11 is fixedly connected to the upper end of the base 2. The tubular plug 11 and the pushing cylinder 37 are coaxially arranged. The tubular plug 11 can be inserted into the grouting hole. When in use, the tubular plug 11 can be directly inserted into the grouting hole, and then when the control component is operated, the grouting nail 4 can be inserted into the grouting hole through the tubular plug 11, facilitating construction operation;

[0051] Furthermore, in order to facilitate loading the grouting nails 4 into the placing cylinder 3 and enable the device to be continuously used for a long time during the construction process, such as Figure 5As shown in the figure, a mounting plate 8 is fixedly connected inside the outer shell 1. A connecting rod 10 arranged along the axial direction of the outer shell 1 is rotatably connected to the lower end of the mounting plate 8. A connecting plate 9 is slidably connected to the surface of the connecting rod 10. The rear end of the connecting plate 9 is fixedly connected to the base 2. One end of the connecting plate 9 facing the connecting rod 10 is provided with a connecting hole in the opposite direction. The opening diameter of the connecting hole is smaller than the inner diameter of the connecting hole. A piston is fixedly connected to the rear end of the connecting rod 10. The diameter of the piston is equal to the inner diameter of the connecting hole. The diameter of the connecting rod 10 is equal to the opening diameter of the connecting hole, so that the piston can only slide inside the connecting hole and cannot slide out of the connecting hole, ensuring the connection between the connecting plate 9 and the connecting rod 10 and preventing disconnection.

[0052] After all the grouting nails 4 inside the placing cylinder 3 are inserted into the grouting holes, the base 2 can be moved backward, thereby driving the placing cylinder 3 to move synchronously. After the placing cylinder 3 is moved out, the placing cylinder 3 is rotated, as Figure 6 shown in the figure, so that the placing cylinder 3 no longer corresponds to the outer shell 1. Then, the grouting nails 4 can be loaded into the placing groove. After the grouting nails 4 are loaded, the placing cylinder 3 is rotated again to make the placing cylinder 3 correspond to the outer shell 1, and the base 2 is moved forward to reset the placing cylinder 3.

[0053] Furthermore, in order to improve the firmness of the base 2 during installation, fixing blocks 12 that can reciprocate outward are slidably connected to the corresponding two sides of the circumferential surface of the base 2. Fixing chutes are respectively opened on the corresponding two sides of the circumferential surface of the base 2. The fixing sliders are respectively slidably connected to the inner sides of the fixing chutes. The inner ends of the fixing blocks 12 are respectively fixedly connected to fixing springs 13. The other ends of the fixing springs 13 are fixedly connected to the base 2. Fixing grooves are respectively opened on the surface of the outer shell 1 corresponding to the fixing blocks 12. The fixing blocks 12 are engaged with the fixing grooves. The base 2 can be fixed by the engagement of the fixing blocks 12 with the fixing grooves, so that the base 2 cannot move. Auxiliary blocks 14 are respectively fixedly connected to the rear ends of the fixing blocks 12. By moving the auxiliary blocks 14, the fixing blocks 12 can be driven to move and compress the fixing springs 13, so that the fixing blocks 12 are disengaged from the engagement with the fixing grooves. After the fixing blocks 12 are disengaged from the fixing grooves, the base 2 can be moved out.

[0054] Furthermore, in order to facilitate the installation of the base 2, the front ends of the fixing blocks 12 are respectively provided with inclined surface structures on the outer sides. The structure of the fixing grooves is the same as that of the fixing blocks 12. When the base 2 is moved forward and installed into the outer shell 1, the inclined surface structures at the front ends of the fixing blocks 12 touch the rear end of the outer shell 1. Under the action of the inclined surface structures, a reaction force can be generated to make the fixing blocks 12 move inward and compress the fixing springs 13. Then, after the fixing blocks 12 correspond to the fixing grooves, the fixing blocks 12 move toward the fixing grooves under the push of the fixing springs 13 and are engaged with the fixing grooves. Since the rear ends of the fixing blocks 12 are flat structures, a blocking effect is achieved to fix the base 2 and prevent the base 2 from disengaging.

[0055] The elastic pushing component includes a push block 5 that is slidably connected to the inside of the placement groove along the radial direction of the placement cylinder 3. First pushing springs 6 are fixedly connected to the left and right ends of the push block 5 respectively. Mounting sliders are fixedly connected to one end of the push block 5 facing the inner wall of the placement groove. Mounting chutes are respectively formed in the inner wall of the placement groove corresponding to the mounting sliders along the moving direction of the push block 5. The mounting sliders are slidably connected to the mounting chutes, enabling the push block 5 to move stably up and down and preventing the push block 5 from disengaging from the placement groove. The first pushing springs 6 are located inside the mounting sliders, and the other ends of the first pushing springs 6 are respectively fixedly connected to the inner ends of the placement groove. The first pushing springs 6 are used to provide a thrust for the push block 5 to move outward. When the grouting nails 4 are loaded into the placement groove, the first pushing springs 6 are in a compressed state. After the upper grouting nail 4 is pushed out, under the elastic push of the first pushing springs 6, the push block 5 can be pushed outward, and the outer grouting nail 4 can be pushed outward, so that the new grouting nail 4 corresponds to the removal hole. Under the thrust of the first pushing springs 6, the push block 5 and the grouting nail 4 as well as between the grouting nails 4 are in a continuously squeezed state. The generated squeezing force can prevent the grouting nails 4 from being unable to be removed from the placement groove without external force; arc surfaces are respectively formed at one end of the push block 5 corresponding to the grouting nails 4. The arc surfaces are used to cooperate with the surface of the grouting nails 4 to provide a larger contact area, thereby increasing the friction force and improving the stability of the grouting nails 4 under the push of the push block 5.

[0056] Further, in order to improve the grouting efficiency of construction workers during construction, a tubular connecting head 36 is fixedly connected to the front end of the pushing cylinder 37. An opening is formed at the front end of the guiding shell 16. The front end of the connecting head 36 extends out of the guiding shell 16 through the opening. The connecting head 36 is used to connect the grouting equipment;

[0057] The connecting head 36 includes a connecting part and an injection part. The inner diameters of the connecting part and the injection part are equal. The rear end opening of the injection part extends to the rear end of the pushing cylinder 37 and is flush with the rear end opening of the pushing cylinder 37, so that after the rear end of the pushing cylinder 37 contacts the grouting nail 4, the slurry can directly enter the grouting nail 4 to ensure the grouting effect; the surface diameter of the connecting part is smaller than the surface diameter of the injection part, which is convenient for the connecting part to connect the pipeline of the grouting equipment and makes the pipeline diameter of the grouting equipment smaller than the front end opening of the guiding shell 16, so that the pipeline of the grouting equipment can smoothly enter and exit the front end opening of the guiding shell 16 during the forward and backward movement of the pushing cylinder 37. After the pushing cylinder 37 moves backward to push the grouting nail 4 into the grouting hole, if grouting is required, the grouting equipment can be started, so that the slurry enters the grouting nail 4 through the connecting head 36 and is injected into the grouting hole through the grouting nail 4, and can be controlled according to the choice of construction workers during use;

[0058] Furthermore, in order to improve the grouting effect, the rear end opening of the injection part contracts inward, making the diameter of the rear end opening of the injection component smaller than that of the front end opening of the connection part. When the grout is ejected through the rear end opening of the injection part, it can be concentrated, which can not only increase the flow rate of the grout passing through the rear end opening of the injection part, avoid the grout from contaminating the pushing cylinder 37, but also further play a pressure boosting effect to improve the grouting effect.

[0059] As Figure 10 shown, a support plate 20 is fixedly connected to the front end of the guiding shell 16. A support slider is fixedly connected to the lower end of the support plate 20. A support sliding groove is formed on the front end surface of the outer shell 1 along the moving direction of the guiding shell 16. The support slider is slidably connected to the support sliding groove. The upper end of the support slider is fixedly connected to a second pushing spring 21. The other end of the second pushing spring 21 is fixedly connected to the inner wall of the support sliding groove. When the support slider is connected to the support sliding groove, the guiding shell 16 is kept connected to the outer shell 1, and under the elastic action of the second pushing spring 21, a restoring driving force is provided for the guiding shell 16 and the guiding shell 16 is supported to ensure the stability of the guiding shell 16;

[0060] Among them, as Figure 11 and Figure 12 shown, a push box 17 that can move up and down is slidably connected to the surface of the guiding shell 16. Push inclined grooves 31 are respectively formed on the left and right side surfaces of the push box 17. An arc-shaped plate 32 that can move along the length direction of the guiding shell 16 is slidably connected to the surface of the guiding shell 16. Limit sliders are respectively fixedly connected to the left and right ends of the arc-shaped plate 32. Limit sliding grooves are formed on the surface of the guiding shell 16 corresponding to the limit sliders along the length direction. The limit sliders are respectively slidably connected to the corresponding limit sliding grooves, so that the arc-shaped plate 32 can move stably. Third pushing springs 34 are respectively fixedly connected to the rear sides of the left and right ends of the arc-shaped plate 32. The third pushing springs 34 are respectively located at the rear end of the arc-shaped plate 32 and are installed in the limit sliding grooves. A moving block is fixedly connected between the arc-shaped plate 32 and the pushing cylinder 37. A moving groove is formed on the upper end of the guiding shell 16 along the length direction. The moving block is slidably connected to the moving groove. Connecting pins 33 are respectively fixedly connected to the left and right ends of the arc-shaped plate 32. The outer ends of the connecting pins 33 are respectively slidably connected to the push inclined grooves 31. When the push box 17 moves downward, the arc-shaped plate 32 can be driven to move through the sliding cooperation between the push inclined grooves 31 and the connecting pins 33, and then the pushing cylinder 37 is driven to move towards the grouting nail 4. During the movement of the arc-shaped plate 32, the third pushing springs 34 can be compressed, and a restoring driving force is provided for the arc-shaped plate 32 through the third pushing springs 34, and then the push box 17 is driven to reset;

[0061] Furthermore, in order to improve the stability of the pushing box 17 during use, vertical mounting rods 18 are fixedly connected to the front and rear sides of the upper end of the guiding shell 16 respectively. The front and rear ends of the pushing box 17 are slidably connected to the mounting rods 18 respectively, ensuring that the pushing box 17 can move up and down stably. The surfaces of the mounting rods 18 are respectively sleeved with first return springs 19, and the first return springs 19 are located below the pushing box 17, further supporting the pushing box 17.

[0062] Furthermore, the placing cylinder 3 has a cross structure, and the placing grooves are respectively opened in the protruding parts of the cross structure of the placing cylinder 3. The guiding shell 16 is slidably fitted on the surface of the protruding part on the upper side of the placing cylinder 3, enabling the guiding shell 16 to be fully fitted with the placing cylinder 3, facilitating the alignment of the pushing cylinder 37 with the grouting nail 4. Rectangular grooves 35 with front openings are respectively opened along the length direction at the outer ends of the placing grooves. The front openings of the rectangular grooves 35 are correspondingly arranged with the moving blocks. When the pushing cylinder 37 moves backward, the rectangular grooves 35 can provide moving channels for the moving blocks, facilitating the movement of the pushing cylinder 37.

[0063] As Figure 9 shown, the control component includes a dial wheel 29 and a grooved wheel 30 meshing with the dial wheel 29. The dial wheel 29 and the grooved wheel 30 are respectively rotatably connected to the mounting plate 8. The grooved wheel 30 and the dial wheel 29 form a 90-degree intermittent transmission mechanism. A motor 15 is arranged below the dial wheel 29, and the motor 15 is fixedly connected to the inner wall of the housing 1. A belt drive structure is connected between the output end of the motor 15 and the dial wheel 29. The belt drive structure includes a first belt pulley 27 fixedly connected to the output end of the motor 15 and a second belt pulley 28 fixedly connected coaxially with the dial wheel 29. A transmission belt is sleeved between the first belt pulley 27 and the second belt pulley 28, used to transmit the power of the motor 15 to the dial wheel 29, controlling the rotation of the dial wheel 29 to drive the grooved wheel 30 to rotate 90 degrees;

[0064] As Figure 10 shown, a first cam 22 is fixedly connected coaxially to the front end of the grooved wheel 30. Four protrusions are evenly opened on the circumferential surface of the first cam 22, and the interval between two adjacent protrusions is 90 degrees. A bearing plate 55 is fixedly connected to the lower side of the front end of the guiding shell 16. The bottom of the bearing plate 55 is slidably fitted with the first cam 22. Whenever the first cam 22 rotates 90 degrees, it can push the bearing plate 55 to move upward once, thereby driving the guiding shell 16 to move upward once, and then the guiding shell 16 is reset under the push of the second pushing spring 21;

[0065] Furthermore, in order to ensure the matching effect between the guiding housing 16 and the placing cylinder 3, a second driving plate 24 is coaxially and fixedly connected to one end of the sprocket 30 away from the first cam 22. The rear end of the second driving plate 24 is coaxially and rotatably connected to a first driving plate 23. A spline shaft 7 is coaxially and fixedly connected to the rear end of the first driving plate 23. A spline hole is formed in the middle of the front end of the placing cylinder 3 and extends backward. The spline shaft 7 is slidably connected to the spline hole for driving the placing cylinder 3 to rotate. When the moving base 2 is moved out of the placing cylinder 3, the spline shaft 7 can be disengaged from the placing cylinder 3, and the spline shaft 7 is inserted into the spline hole when the placing cylinder 3 is reinstalled, facilitating the rotation of the placing cylinder. An arc-shaped mating chute is formed on the rear surface of the second driving plate 24. An arc-shaped spring 26 is arranged inside the mating chute. A mating slider 25 is fixedly connected to the front end of the first driving plate 23. The mating slider 25 is slidably connected to the mating chute. The arc-shaped spring 26 is located on one side of the mating block. When the dial 29 rotates, it drives the sprocket 30 to rotate through meshing with the sprocket 30. When the sprocket 30 rotates, it first drives the first cam 22 to rotate. There is a certain interval between two adjacent protrusions of the first cam 22. During the rotation of the first cam 22, the lower end of the bearing plate 55 slides on the surface of the interval between two adjacent protrusions of the first cam 22. At the same time, during the rotation of the sprocket 30, it drives the second driving plate 24 to rotate synchronously. Since the guiding housing 16 is slidably matched with the placing cylinder 3, the placing cylinder 3 cannot rotate. Therefore, when the second driving plate 24 rotates, it cannot drive the first driving plate 23 to rotate, and thus the arc-shaped spring 26 is compressed during rotation, causing the arc-shaped spring 26 to store energy. When the protruding part on the circumferential surface of the first cam 22 contacts the bearing plate 55, it can push the bearing plate 55 upward and drive the guiding housing 16 upward. When the top of the protruding part on the circumferential surface of the first cam 22 corresponds to the top of the bearing plate 55, the guiding housing 16 disengages from the placing cylinder 3, and the placing cylinder 3 resumes the rotation effect. The first driving plate 23 can rotate simultaneously. Then, the first driving plate 23 rotates rapidly under the push of the arc-shaped spring 26. When the sprocket 30 rotates 90 degrees, the placing cylinder 3 rotates 90 degrees synchronously, so that the new placing groove rotates to the upper side, and the bottom of the bearing plate 55 is disengaged from the protruding part of the first cam 22. The guiding housing 16 moves downward and resets under the push of the second pushing spring 21 and re-matches with the placing cylinder 3. Among them, one side of the protrusion on the circumferential surface of the second cam 54 is an inclined surface, and the other side is a vertically arranged plane. The inclined surface part of the protrusion is used to push the bearing plate 55 to move. After the sprocket 30 drives the placing cylinder 3 to rotate 90 degrees, the bearing plate 55 disengages from the inclined surface part of the protrusion, and the guiding housing 16 can quickly reset and cooperate with the placing cylinder 3 under the push of the second pushing spring 21, ensuring the precise cooperation between the placing cylinder 3 and the guiding housing 16.

[0066] Further, in order to facilitate the control of the movement of the pushing cylinder 37 and enable the grouting nail 4 to be automatically pushed out, a second cam 54 is coaxially and fixedly connected to the front end of the dial 29. When the dial 29 rotates, the second cam 54 rotates synchronously. A frame-shaped frame 50 is arranged on the front side of the second cam 54. A triangular block 53 is fixedly connected to the rear end of the frame-shaped frame 50. The triangular block 53 is slidably engaged with the second cam 54. As Figure 15 shown, during the process of the dial 29 rotating towards the ratchet wheel 30 and engaging with the ratchet wheel 30, the triangular block 53 slides on the non-protruding part of the surface of the second cam 54 and will not affect the frame-shaped frame 50. After the dial 29 drives the ratchet wheel 30 to rotate, the pushing cylinder 37 is located in front of the new grouting nail 4. During the continuous rotation of the dial 29, the protruding part of the circumferential surface of the second cam 54 can rotate towards the triangular block 53 and drive the frame-shaped frame 50 to move downward by pushing the triangular block 53;

[0067] One-way connection components are connected between the left and right sides of the upper end of the frame-shaped frame 50 and the pushing box 17. When the guiding shell 16 drives the pushing box 17 to move up and down, the frame-shaped frame 50 is not driven. When the frame-shaped frame 50 moves up and down, it can drive the pushing box 17 to move up and down through the one-way connection components, and then drive the pushing cylinder 37 to move backward to push out the grouting nail 4. After the protruding part of the circumferential surface of the second cam 54 disengages from the triangular block 53, the pushing box 17 moves upward to reset and drives the frame-shaped frame 50 to move upward to reset, forming that after the guiding shell 16 moves upward, the placing cylinder 3 rotates 90 degrees to replace a new grouting nail 4. The guiding shell 16 then moves downward to reset so that the pushing cylinder 37 corresponds to the new grouting nail 4. Then the pushing box 17 moves downward and reciprocates once to control the pushing cylinder 37 to push out the corresponding grouting nail 4 at the rear side. This cycle continues, so that all the grouting nails 4 in the placing groove are pushed out during the intermittent rotation of the placing cylinder 3; and when the triangular block 53 is on the protruding part of the circumferential surface of the second cam 54, the pushing cylinder 37 is in a state of being in close contact with one end of the grouting nail 4. At this time, the construction personnel can choose whether to start the grouting equipment to inject grout into the grouting hole.

[0068] Further, as Figure 16 shown, the one-way connection components include sliding plates 40 that are slidably connected to the left and right sides of the mounting plate 8 and can move up and down. Rotating plates 41 are respectively rotatably connected to the front end surfaces of the sliding plates 40. Elastic support members for supporting the rotating plates 41 are respectively installed on the surfaces of the sliding plates 40. The elastic support members are used to support the rotating plates 41 so that the support plate 20 can maintain balance and stability;

[0069] A baffle 39 is fixedly connected to the circumferential surface of the rotating plate 41 respectively. Hooks 38 are fixedly connected to the left and right sides of the lower end of the pushing box 17 respectively. The baffle 39 is located above the hooks 38. When the guiding shell 16 drives the pushing box 17 to move up and down, the hooks 38 can move up and down synchronously with the pushing box 17. At this time, the rotating plate 41 is in a rotatable state. During the up and down movement of the hooks 38, the baffle 39 cannot play a blocking role, and the rotating plate 41 can be reset under the support of the elastic support member. Therefore, the pushing box 17 can move up and down freely.

[0070] Stopping grooves 42 are respectively opened downward on the upper side of the circumferential surface of the rotating plate 41. Stopping insertion plates 47 that can be inserted into the stopping grooves 42 are fixedly connected to the left and right sides of the rear end of the frame-shaped frame 50 respectively. The stopping insertion plates 47 and the stopping grooves 42 are arranged corresponding to each other up and down.

[0071] When the frame-shaped frame 50 moves downward under the push of the second cam 54, it can drive the stopping insertion plates 47 to move downward, so that the stopping insertion plates 47 are inserted into the stopping grooves 42, thereby braking the rotating plate 41 to make the rotating plate 41 unable to rotate. Therefore, the baffle 39 can play a blocking role. During the downward movement of the frame-shaped frame 50, it can drive the sliding plate 40 to move downward synchronously. During the downward movement of the sliding plate 40, it can drive the rotating plate 41 and the baffle 39 to move downward synchronously, and drive the pushing box 17 to move downward through the connection between the baffle 39 and the hooks 38, so as to realize the function of driving the pushing cylinder 37 to move. The rear ends of the sliding plates 40 are respectively slidably connected with reset sliders. Reset sliding grooves are respectively opened along the length direction on the left and right sides of the front surface of the mounting plate 8. The reset sliders are slidably connected with the reset sliding grooves. Third reset springs 52 are fixedly connected to the lower ends of the reset sliders respectively. The lower ends of the third reset springs 52 are respectively fixedly connected to the inner walls of the reset sliding grooves. During the downward movement of the sliding plate 40, the third reset springs 52 will be compressed, and the third reset springs 52 can play a role in supporting the sliding plate 40, ensuring the stability of the sliding plate 40, and providing resistance when the sliding plate 40 is reset.

[0072] The upper end of the sliding plate 40 is provided with a mating hole opening downward. A mating rod 48 is axially slidably connected inside the mating hole. A second return spring 49 is fixedly connected between the mating rod 48 and the inner wall of the mating hole. The outer end of the mating rod 48 is fixedly connected to the stop plug 47 respectively. Under the sliding connection between the mating rod 48 and the mating hole, the stop plug 47 and the sliding plate 40 can be kept connected, and under the action of the second return spring 49, the stop plug 47 and the baffle 39 can be kept at a certain distance, so as to avoid the stop plug 47 blocking the swing of the baffle 39 when the rotating plate 41 rotates, and can support the frame-shaped frame 50 and help to push the frame-shaped frame 50 to reset. Among them, the elastic coefficient of the second return spring 49 is smaller than that of the third return spring 52. When the frame-shaped frame 50 moves downward and squeezes the second return spring 49 through the mating rod 48, the driving force generated is not enough to overcome the elastic force of the third return spring 52. Therefore, when the frame-shaped frame 50 moves downward and squeezes the second return spring 49, the sliding plate 40 will not move under the support of the third return spring 52, so that the stop plug 47 is inserted into the stop groove 42 to brake the rotating plate 41, and then the driving force generated when the frame-shaped frame 50 continues to move downward can overcome the elastic force of the third return spring 52 and push the sliding plate 40 to move downward, playing a role in maintaining the function of the second return spring 49 while ensuring the linkage of the baffle 39 driving the hook 38 to move.

[0073] Further, the elastic support member includes a swing plate 43 fixedly connected coaxially to the rear end of the rotating plate 41. An activity groove 44 is formed in the surface of the swing plate 43 along the length direction. A linkage pin shaft 45 is slidably fitted inside the activity groove 44. A linkage slider is fixedly connected to the rear end of the linkage pin shaft 45. The linkage slider is vertically slidably connected to the mounting plate 8. Support springs 46 are fixedly connected to the upper and lower ends of the linkage slider respectively. The other ends of the support springs 46 are fixedly connected to the mounting plate 8. When the guiding shell 16 drives the pushing box 17 to move up and down, when the hook 38 continuously pushes the baffle 39 to swing up and down around the axis of the rotating plate 41 during the synchronous up and down movement with the pushing box 17, the swing plate 43 will also swing synchronously, and drive the linkage slider to move up and down under the sliding fit of the activity groove 44 and the linkage pin shaft 45. During the up and down movement of the linkage slider, the support springs 46 will be continuously squeezed, and reset under the push of the support springs 46. Under the elastic support of the support springs 46, when the hook 38 disengages from the baffle 39, the baffle 39 can reset, so that the stop groove 42 always corresponds to the stop plug 47, ensuring that the stop plug 47 can engage with the stop groove 42 when the frame-shaped frame 50 moves downward, completing the braking effect on the rotating plate 41; during the use of this device, in order to make it more convenient for construction workers to operate and use, a grip rod is fixedly connected to the lower end of the outer shell 1 along the length direction of the outer shell 1 for facilitating the construction workers to carry this device. A first handle vertically arranged is fixedly connected to the lower end of the grip rod. A second handle is fixedly connected to the front side of the upper end of the outer shell. When using this device, construction workers can hold the first handle and the second handle simultaneously to improve the stability during the use of this device and facilitate construction workers to carry out construction.
