[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; 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.

DETAILED DESCRIPTION

[0032] 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.

[0033] 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. Furthermore, a push-injection component that can move up and down is provided on the upper side of the placement cylinder 3, and a control component that can control the placement cylinder 3 to rotate intermittently and the push-injection component to move up and down alternately is installed at the front end of the inner part of the housing 1. Under the control of the control component, the placement cylinder 3 rotates intermittently once every time the push-injection component moves upward, and then the push-injection component moves downward and resets; The pushing component includes a guide shell 16 which is slidably connected to the outer shell 1 and can move up and down. The inside of the guide shell 16 is slidably connected with a pushing cylinder 37 which can move forward and backward. The pushing cylinder 37 is a hollow structure with openings at both ends. The diameter of the pushing cylinder 37 is equal to the diameter of the grouting nail 4, and the grouting nail 4 can be connected to the grouting nail 4 while being able to push the grouting nail 4. The pushing cylinder 37 is located at the front side of the placement cylinder 3. Whenever the placement cylinder 3 rotates once, the grouting nail 4 whose placement slot is located at the outermost side is correspondingly arranged with the pushing cylinder 37. The grouting nail 4 is pushed out of the placement slot by the pushing cylinder 37. When in use, the device aligns the removal hole with the grouting hole. By operating the control component, the grouting nail 4 inside the placement cylinder 3 can be automatically inserted into the grouting hole, which saves the construction personnel the operating steps of manually inserting the grouting nail 4 into the grouting hole one by one, and replaces the manual force with mechanical power, which not only greatly improves the construction efficiency, but also effectively saves manpower and reduces the workload of the construction personnel. The grouting nails 4 are loaded into the placement cylinder 3 respectively, which is convenient to carry and can achieve the effect of taking and using at any time.

[0034] Furthermore, in order to facilitate the construction personnel to control the device to align the removal hole with the grouting hole, the rear end of the shell 1 is slidably matched with a base 2 that can move forward and backward, the rear end of the placement tube 3 is rotatably connected to the middle of the base 2, and the upper end of the base 2 is fixedly connected with a tubular plug 11, the tubular plug 11 and the push tube 37 are coaxially arranged, and 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 operating the control component, the grouting nail 4 can be inserted into the grouting hole through the tubular plug 11, which is convenient for construction operation; Furthermore, in order to facilitate the filling of the grouting nails 4 into the placement tube 3, the device can be used continuously for a long time during the construction process. Figure 5 As shown, a mounting plate 8 is fixedly connected inside the housing 1, and a connecting rod 10 arranged along the axial direction of the housing 1 is rotatably connected to the lower end of the mounting plate 8, and a connecting plate 9 is slidably connected to the surface of the connecting rod 10, and the rear end of the connecting plate 9 is fixedly connected to the base 2, and the connecting plate 9 is provided with a connecting hole in the opposite direction toward one end of the connecting rod 10, and the opening diameter of the connecting hole is smaller than the inner diameter of the connecting hole, and a piston is fixedly connected to the rear end of the connecting rod 10, and the diameter of the piston is equal to the inner diameter of the connecting hole, and 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, but cannot slide out of the connecting hole, thereby ensuring the connection between the connecting plate 9 and the connecting rod 10 and avoiding separation; After all the grouting nails 4 in the placement tube 3 are inserted into the grouting holes, the base 2 can be moved backward to drive the placement tube 3 to move synchronously. After the placement tube 3 is moved out, the placement tube 3 is rotated. Figure 6 As shown, the placement tube 3 is no longer in correspondence with the housing 1, and then the grouting nails 4 can be filled into the placement groove. After the grouting nails 4 are filled, the placement tube 3 is rotated to make the placement tube 3 correspond to the housing 1, and the base 2 is moved forward to reset the placement tube 3; Furthermore, in order to improve the firmness of the base 2 during installation, the two sides corresponding to the circumferential surface of the base 2 are respectively slidably connected with fixed blocks 12 that can reciprocate outward, and the two sides corresponding to the circumferential surface of the base 2 are respectively provided with fixed slide grooves, and the fixed sliders are respectively slidably connected to the inner sides of the fixed slide grooves, and the inner ends of the fixed blocks 12 are respectively fixedly connected with fixed springs 13, and the other ends of the fixed springs 13 are fixedly connected to the base 2, and the surfaces of the shell 1 corresponding to the fixed blocks 12 are respectively provided with fixed grooves, and the fixed blocks 12 are meshed with the fixed grooves, and the base 2 can be fixed by the meshing of the fixed blocks 12 with the fixed grooves, so that the base 2 cannot move, and the rear ends of the fixed blocks 12 are respectively fixedly connected with auxiliary blocks 14, and the auxiliary blocks 14 can be moved to drive the fixed blocks 12 to move and squeeze the fixed springs 13, so that the fixed blocks 12 are disengaged from the fixed grooves, and the base 2 can be moved out after the fixed blocks 12 are disengaged from the fixed grooves; Furthermore, in order to facilitate the installation of the base 2, the front end of the fixing block 12 is opened outward as an inclined structure, and the structure of the fixing groove is the same as that of the fixing block 12. When the base 2 is moved forward to install the base 2 in the shell 1, the inclined structure at the front end of the fixing block 12 touches the rear end of the shell 1. Under the action of the inclined structure, a reverse thrust can be generated to move the fixing block 12 inward and squeeze the fixing spring 13. Then, after the fixing block 12 corresponds to the fixing groove, the fixing block 12 moves in the direction of the fixing groove under the push of the fixing spring 13 and engages with the fixing groove. Since the rear end of the fixing block 12 is a planar structure, it plays a blocking role to fix the base 2 and prevent the base 2 from detaching.

[0035] The elastic pushing component includes a pushing block 5 that is slidably connected to the inside of the placement groove along the radial direction of the placement tube 3, and the left and right ends of the pushing block 5 are respectively fixedly connected to the first pushing spring 6, and one end of the pushing block 5 facing the inner wall of the placement groove is respectively fixedly connected to the installation slide block, and the inner wall of the placement groove corresponding to the installation slide block is respectively provided with an installation slide groove along the moving direction of the pushing block 5, and the installation slide block is slidably connected to the installation slide groove, so that the pushing block 5 can move up and down stably and prevent the pushing block 5 from leaving the placement groove. The first pushing spring 6 is located on the inner side of the installation slide block, and the other end of the first pushing spring 6 is respectively fixedly connected to the inner end of the placement groove. The first pushing spring 6 is used to provide a thrust for the pushing block 5 to move outward. When the grouting nail 4 is filled in the placement groove, the first pushing spring 6 A push spring 6 is in a compressed state. After the grouting nail 4 on the upper side is pushed out, the push block 5 can be pushed to move outward under the elastic push of the first push spring 6, and the grouting nail 4 on the outside can be pushed outward, so that the new grouting nail 4 corresponds to the removal hole, and the push block 5 and the grouting nail 4 and the grouting nail 4 are in a state of continuous squeezing under the push of the first push spring 6. The generated squeezing force can prevent the grouting nail 4 from being unable to move out of the placement groove without being pushed by external force; the push block 5 and the grouting nail 4 are respectively provided with an arc surface at one end corresponding to the grouting nail 4, which is used to cooperate with the surface of the grouting nail 4 to provide a larger contact area, thereby increasing the friction and improving the stability of the grouting nail 4 under the push of the push block 5.

[0036] Furthermore, in order to improve the grouting efficiency of the construction workers during construction, the front end of the push cylinder 37 is fixedly connected with a tubular connector 36, the front end of the guide housing 16 is provided with an opening, the front end of the connector 36 extends out of the guide housing 16 through the opening, and the connector 36 is used to connect the grouting equipment; The connecting head 36 includes a connecting component 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 push cylinder 37 and is flush with the rear end opening of the push cylinder 37, so that after the rear end of the push 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 the pipeline diameter of the grouting equipment is smaller than the front end opening of the guide shell 16, so that the pipeline of the grouting equipment can smoothly enter and exit the front end opening of the guide shell 16 during the forward and backward movement of the push cylinder 37. After the push cylinder 37 moves to the rear side to push the grouting nail 4 into the grouting hole, if grouting is required, the grouting equipment can be started to allow the slurry to enter the grouting nail 4 through the connecting head 36 and be injected into the grouting hole through the grouting nail 4. When in use, it can be controlled according to the choice of the construction personnel; Furthermore, in order to improve the grouting effect, the rear end opening of the injection part is contracted inwardly, so that the diameter of the rear end opening of the injection part is smaller than the front end opening of the connecting part, so that the slurry can be sprayed in a concentrated manner when it is ejected through the rear end opening of the injection part. This can not only increase the flow rate of the slurry when it passes through the rear end opening of the injection part and prevent the slurry from contaminating the push cylinder 37, but also further achieve a pressurization effect to improve the grouting effect.

[0037] like Fig.10 As shown, the front end of the guide housing 16 is fixedly connected with a support plate 20, the lower end of the support plate 20 is fixedly connected with a support slider, the front end surface of the housing 1 is provided with a support slot along the moving direction of the guide housing 16, the support slider is slidably connected with the support slot, the upper end of the support slider is fixedly connected with a second push spring 21, the other end of the second push spring 21 is fixedly connected with the inner wall of the support slot, when the support slider is connected with the support slot, the guide housing 16 is kept connected with the housing 1, and under the elastic action of the second push spring 21, a driving force for resetting the guide housing 16 is provided, and the guide housing 16 is supported to ensure the stability of the guide housing 16; Among them Fig.11 and Fig.12 As shown, the surface of the guide shell 16 is slidably connected with a push box 17 that can move up and down, and the left and right side surfaces of the push box 17 are respectively provided with push inclined grooves 31. The surface of the guide shell 16 is slidably connected with an arc plate 32 that can move along the length direction of the guide shell 16. The left and right ends of the arc plate 32 are respectively fixedly connected to limit sliders. The surface of the guide shell 16 corresponding to the limit slider is provided with limit sliding grooves along the length direction. The limit sliders are respectively slidably connected with the corresponding limit sliding grooves, so that the arc plate 32 can move stably. The rear sides of the left and right ends of the arc plate 32 are respectively fixedly connected with third push springs 34. The third push springs 34 are respectively located at the rear ends of the arc plate 32, and the third push springs 34 are installed at the limit sliders. The upper end of the guide shell 16 is provided with a moving groove along the length direction, and the moving block is slidably connected with the moving groove. The left and right ends of the arc plate 32 are respectively fixedly connected with connecting pins 33, and the outer ends of the connecting pins 33 are respectively slidably connected with the push inclined groove 31. When the push box 17 moves downward, the arc plate 32 can be driven to move by the sliding cooperation between the push inclined groove 31 and the connecting pin 33, thereby driving the push tube 37 to move toward the grouting nail 4. In the process of the movement of the arc plate 32, the third push spring 34 can be squeezed, and the third push spring 34 provides the arc plate 32 with a driving force for resetting, thereby driving the push box 17 to reset. Furthermore, in order to improve the stability of the push box 17 when in use, the front and rear sides of the upper end of the guide shell 16 are respectively fixedly connected with vertically arranged mounting rods 18, and the front and rear ends of the push box 17 are respectively slidably connected with the mounting rods 18 to ensure that the push box 17 can move up and down stably. The surface of the mounting rods 18 is respectively covered with a first return spring 19, and the first return spring 19 is located on the lower side of the push box 17, so as to further support the push box 17.

[0038] Furthermore, the placement tube 3 is in a cross structure, and the placement grooves are respectively opened in the raised parts of the cross structure of the placement tube 3. The guide shell 16 slides and fits on the raised part surface on the upper side of the placement tube 3, so that the guide shell 16 can fully cooperate with the placement tube 3, which is convenient for the correspondence between the pushing tube 37 and the grouting nail 4. The outer ends of the placement grooves are respectively provided with rectangular grooves 35 with front end openings along the length direction. The front end openings of the rectangular grooves 35 are arranged corresponding to the moving block. When the pushing tube 37 moves to the rear side, the rectangular grooves 35 can serve as a moving channel for the moving block, which is convenient for the movement of the pushing tube 37.

[0039] like Fig. 9 As shown, the control component includes a paddle wheel 29 and a groove wheel 30 meshing with the paddle wheel 29, the paddle wheel 29 and the groove wheel 30 are respectively rotatably connected to the mounting plate 8, the groove wheel 30 and the paddle wheel 29 constitute a 90-degree intermittent transmission mechanism, a motor 15 is arranged at the lower side of the paddle wheel 29, the motor 15 is fixedly connected to the inner wall of the housing 1, a pulley transmission structure is connected between the output end of the motor 15 and the paddle wheel 29, the pulley transmission structure includes a first pulley 27 fixedly connected to the output end of the motor 15 and a second pulley 28 coaxially fixedly connected to the paddle wheel 29, a transmission belt is sleeved between the first pulley 27 and the second pulley 28, for transmitting the power of the motor 15 to the paddle wheel 29, and controlling the rotation of the paddle wheel 29 drives the groove wheel 30 to rotate 90 degrees; like Fig.10 As shown, the front end of the groove wheel 30 is coaxially fixedly connected with the first cam 22, and the circumferential surface of the first cam 22 is evenly provided with four protrusions, and the interval between two adjacent protrusions is 90 degrees. A pressure plate 55 is fixedly connected to the lower side of the front end of the guide housing 16, and the bottom of the pressure plate 55 is slidably matched with the first cam 22. Whenever the first cam 22 rotates 90 degrees, it can push the pressure plate 55 to move upward once, thereby driving the guide housing 16 to move upward once, and then the guide housing 16 is reset under the push of the second push spring 21; Furthermore, in order to ensure the coordination effect between the guide housing 16 and the placement cylinder 3, the end of the groove wheel 30 away from the first cam 22 is coaxially fixedly connected to the second drive plate 24, and the rear end of the second drive plate 24 is coaxially rotatably connected to the first drive plate 23. The rear end of the first drive plate 23 is coaxially fixedly connected to a spline shaft 7, and a spline hole is provided in the middle of the front end of the placement cylinder 3 to the rear end. The spline shaft 7 is slidably connected to the spline hole and is used to transmit the placement cylinder 3 and drive the placement cylinder 3 to rotate. When the mobile base 2 moves out of the placement cylinder 3, the spline shaft 7 can be separated from the placement cylinder 3. When the placement cylinder 3 is reinstalled, the spline shaft 7 is inserted into the spline hole to facilitate the rotation of the placement cylinder; the rear end surface of the second drive plate 24 is provided with a The arc-shaped matching groove has an arc spring 26 arranged inside the matching groove. A matching slider 25 is fixedly connected to the front end of the first driving plate 23. The matching slider 25 is slidably connected to the matching groove. The arc spring 26 is located on one side of the matching block. When the thumbwheel 29 rotates, the groove wheel 30 is driven to rotate by meshing with the groove wheel 30. When the groove wheel 30 rotates, the first cam 22 is first driven to rotate. There is a certain interval between the two adjacent protrusions of the first cam 22. During the rotation of the first cam 22, the lower end of the pressure plate 55 slides on the interval surface between the two adjacent protrusions of the first cam 22. At the same time, during the rotation of the groove wheel 30, the second driving plate 24 is driven to rotate synchronously. When the second driving plate 24 rotates When the first drive plate 23 is rotated, the first drive plate 23 is not able to rotate, and the arc spring 26 is squeezed while rotating, so that the arc spring 26 accumulates force. When the raised portion of the circumferential surface of the first cam 22 contacts the pressure plate 55, the pressure plate 55 is pushed to move upward, and the guide housing 16 is driven to move upward. When the top of the raised portion of the circumferential surface of the first cam 22 corresponds to the top of the pressure plate 55, the guide housing 16 is separated from the placement cylinder 3, and the placement cylinder 3 resumes the rotation effect. The first drive plate 23 can rotate at the same time, and then the first drive plate 23 is quickly rotated under the push of the arc spring 26. When the groove wheel 30 rotates ninety degrees, the placement cylinder 3 rotates ninety degrees synchronously, so that the new placement groove rotates to the upper side, and the bottom of the pressure plate 55 is disconnected from the protruding part of the first cam 22, and the guide shell 16 moves downward and resets under the push of the second push spring 21, and re-matches with the placement cylinder 3, wherein 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 set plane, and the raised inclined surface part is used to push the pressure plate 55 to move, and after the groove wheel 30 drives the placement cylinder 3 to rotate ninety degrees, the pressure plate 55 is separated from the raised inclined surface part, and the guide shell 16 can be quickly reset under the push of the second push spring 21 to keep matching with the placement cylinder 3, thereby ensuring the precise matching between the placement cylinder 3 and the guide shell 16.

[0040] Furthermore, in order to facilitate the control of the movement of the push tube 37 so that the grouting nail 4 can be automatically pushed out, the front end of the dial wheel 29 is coaxially fixedly connected to a second cam 54, and the second cam 54 rotates synchronously when the dial wheel 29 rotates. A frame 50 is provided on the front side of the second cam 54, and a triangular block 53 is fixedly connected to the rear end of the frame 50. The triangular block 53 is slidably matched with the second cam 54, as shown in FIG. Fig.15 As shown, in the process that the thumbwheel 29 rotates toward the groove wheel 30 to mesh with the groove wheel 30, the triangular block 53 slides on the non-protruding part of the second cam 54, and will not affect the frame 50. After the thumbwheel 29 drives the groove wheel 30 to rotate, the push cylinder 37 is located at the front side of the new grouting nail 4. In the process that the thumbwheel 29 continues to rotate, the protruding part of the circumferential surface of the second cam 54 can rotate toward the triangular block 53, and drive the frame 50 to move downward by pushing the triangular block 53. The left and right sides of the upper end of the frame 50 are connected to the push box 17 with a one-way connection component. When the guide housing 16 drives the push box 17 to move up and down, the frame 50 is not driven. When the frame 50 moves up and down, the push box 17 can be driven up and down by the one-way connection component, thereby driving the push tube 37 to move backward to push out the grouting nail 4. After the protruding part of the circumferential surface of the second cam 54 is separated from the triangular block 53, the push box 17 moves upward to reset, and drives the frame 50 to move upward to reset, so that when the guide housing 16 moves upward, the tube 3 is placed for nine After ten degrees of rotation, a new grouting nail 4 is replaced, and the guide shell 16 moves downward and resets to make the push cylinder 37 correspond to the new grouting nail 4. Then the push box 17 moves downward and reciprocates once to control the push cylinder 37 to push out the corresponding grouting nail 4 on the rear side, and repeats this cycle over and over again, so that the placement cylinder 3 can push out all the grouting nails 4 in the placement groove during the intermittent rotation; and when the triangular block 53 is on the protruding part of the circumferential surface of the second cam 54, the push cylinder 37 is in a state of close contact with one end of the grouting nail 4, so that the construction personnel can choose whether to start the grouting equipment to grout into the grouting hole.

[0041] Further, such as Fig.16 As shown, the one-way connection component includes a sliding plate 40 that is slidably connected to the left and right sides of the mounting plate 8 and can move up and down, and the front end surface of the sliding plate 40 is respectively rotatably connected to a rotating plate 41, and the surface of the sliding plate 40 is respectively installed with an elastic support member for supporting the rotating plate 41, and the elastic support member is used to support the rotating plate 41 so that the support plate 20 can maintain balance and stability; A baffle 39 is fixedly connected to the circumferential surface of the rotating plate 41, and hooks 38 are fixedly connected to the left and right sides of the lower end of the push box 17, respectively. The baffle 39 is located on the upper side of the hook 38; when the guide shell 16 drives the push box 17 to move up and down, the hook 38 can move up and down synchronously with the push box 17. At this time, the rotating plate 41 is in a state of being able to rotate. When the hook 38 moves up and down, the baffle 39 cannot play a blocking role, and the rotating plate 41 can be reset under the support of the elastic support member, so the push box 17 can move up and down freely; The upper side of the circumferential surface of the rotating plate 41 is respectively provided with a stop groove 42 downwardly, and the left and right sides of the rear end of the frame 50 are respectively fixedly connected with a stop plug 47 capable of being inserted into the stop groove 42, and the stop plug 47 is arranged correspondingly to the stop groove 42 up and down; When the frame 50 is pushed downward by the second cam 54, it can drive the stop plate 47 to move downward, so that the stop plate 47 is inserted into the stop groove 42, and then the rotating plate 41 is braked to prevent the rotating plate 41 from rotating. Therefore, the baffle 39 can play a blocking role. In the process of the frame 50 moving downward, the sliding plate 40 can be driven to move downward synchronously. In the process of the sliding plate 40 moving downward, the rotating plate 41 and the baffle 39 can be driven to move downward synchronously, and the push box 17 is driven downward by the connection between the baffle 39 and the hook 38, so as to drive the push cylinder 37 to move downward. The rear end of the sliding plate 40 is respectively slidably connected with a reset slider, and the left and right sides of the front end surface of the mounting plate 8 are respectively provided with a reset slide groove along the length direction, and the reset slider is slidably connected with the reset slide groove, and the lower end of the reset slider is respectively fixedly connected with a third reset spring 52, and the lower end of the third reset spring 52 is respectively fixedly connected with the inner wall of the reset slide groove. When the sliding plate 40 moves downward, the third reset spring 52 will be squeezed, and the third reset spring 52 can play the effect of supporting the sliding plate 40, ensuring the stability of the sliding plate 40, and providing resistance when the sliding plate 40 is reset; A matching hole is downwardly opened at the upper end of the sliding plate 40, and a matching rod 48 is axially slidably connected inside the matching hole. A second return spring 49 is fixedly connected between the matching rod 48 and the inner wall of the matching hole, and the outer ends of the matching rods 48 are fixedly connected to the stop plug plates 47 respectively. Under the sliding connection between the matching rods 48 and the matching holes, the stop plug plates 47 and the sliding plate 40 can be kept connected, and under the action of the second return spring 49, the stop plug plates 47 and the baffle plate 39 can be kept at a certain distance to prevent the stop plug plates 47 from blocking the swing of the baffle plate 39 when the rotating plate 41 rotates, and the frame frame 50 can be supported and helped to push the frame frame 50 to reset, wherein the elastic coefficient of the second return spring 49 is small Due to the elastic coefficient of the third return spring 52, the driving force generated when the frame 50 moves downward and squeezes the second return spring 49 through the matching rod 48 is not enough to overcome the elastic force of the third return spring 52. Therefore, when the 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 plate 47 can be inserted into the stop groove 42 to brake the rotating plate 41, and then the driving force generated when the 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, thereby maintaining the effect of the second return spring 49 while ensuring the linkage of the baffle 39 to drive the hook 38 to move.

[0042] Furthermore, the elastic support members include swing plates 43 respectively fixedly connected to the rear ends of the rotating plate 41 coaxially, a movable groove 44 is provided on the surface of the swing plate 43 along the length direction, a linkage pin 45 is slidably fitted inside the movable groove 44, a linkage slider is fixedly connected to the rear end of the linkage pin 45, the linkage slider is vertically slidably connected to the mounting plate 8, the upper and lower ends of the linkage slider are respectively fixedly connected to support springs 46, the other ends of the support springs 46 are respectively fixedly connected to the mounting plate 8, when the guide shell 16 drives the push box 17 to move up and down, when the hook 38 continuously pushes the baffle plate 39 to swing up and down with the axis of the rotating plate 41 as the center during the synchronous up and down movement of the push box 17, the swing plate 43 will also swing synchronously, and drive the linkage slider to move up and down under the sliding cooperation of the movable groove 44 and the linkage pin 45, and during the up and down movement of the linkage slider The support spring 46 will be continuously squeezed and reset under the push of the support spring 46. Under the elastic support of the support spring 46, the baffle plate 39 can be reset when the hook 38 is separated from the baffle plate 39, so that the stop groove 42 always corresponds to the stop plug plate 47, ensuring that the stop plug plate 47 can engage with the stop groove 42 when the frame 50 moves downward, thereby completing the braking effect on the rotating plate 41. During the use of the device, in order to facilitate the operation and use of the construction personnel, the lower end of the shell 1 is fixedly connected to a grip rod along the length direction of the shell 1, which is used for the construction personnel to carry the device. The lower end of the grip rod is fixedly connected to a vertically arranged first handle, and the upper front side of the shell is fixedly connected to a second handle. When using the device, the construction personnel can hold the first handle and the second handle at the same time, thereby improving the stability when using the device and facilitating the construction personnel to carry out construction.
