Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grouting construction equipment, in particular to a basement waterproof construction device. BACKGROUND

[0002] In basement engineering, waterproofing is a core link related to structural safety and use function. Due to the deep burial of the basement underground, it is easy to have water leakage problems due to the influence of factors such as underground water pressure, concrete shrinkage cracks, and improper construction joint treatment. The grouting machine is the key equipment for solving the waterproofing problem of the basement, which can quickly seal existing leakage points and prevent potential hazards.

[0049] The following refers to Figures 1-15To describe the basement waterproof construction device provided by the application.

[0050] The basement waterproof construction device is suitable for basement waterproof operation, comprising a grouting machine body 100, a grouting pipe 110 connected to the grouting machine body 100, slurry in the grouting machine body 100 being extruded to the grouting pipe 110 under pressure, the grouting pipe 110 being used for conveying grouting liquid, a grouting nail 120 being used for being inserted into a wall body needing grouting and being inserted into a grouting opening of the wall body, one end of the grouting nail 120 being inserted into the wall body, a hinged joint 130 being arranged on the other end of the grouting nail 120, a tallow head 200 being detachably connected to the hinged joint 130, one end of the tallow head 200 being connected to the hinged joint 130 of the grouting nail 120, the other end of the tallow head 200 being connected to the grouting pipe 110, the grouting pipe 110 injecting the slurry into the wall body through the tallow head 200 and the grouting nail 120 to fill cracks and gaps in the wall body.

[0051] The tallow head 200 comprises a shell 210, one end of the shell 210 being connected to the grouting pipe 110, an air passage sleeve 220 being axially elastically slid in the shell 210, the air passage sleeve 220 having a passage in the inside, the passage being communicated with the grouting pipe 110, a plurality of elastic clamping pieces 230 being uniformly distributed in the periphery of the air passage sleeve 220, four elastic clamping pieces 230 being arranged in the embodiment, one end of the plurality of elastic clamping pieces 230 having an arc, a clamping ring 240 being arranged in the periphery of the plurality of elastic clamping pieces 230, the clamping ring 240 being used for clamping the plurality of elastic clamping pieces 230 together, when the grouting nail 120 and the tallow head 200 are connected, the hinged joint 130 of the grouting nail 120 is abutted against one end of the air passage sleeve 220, at this time, the end of the plurality of elastic clamping pieces 230 in the periphery of the air passage sleeve 220 having the arc can clamp the hinged joint 130, when the plurality of elastic clamping pieces 230 are clamped together through the clamping ring 240, the end of the plurality of elastic clamping pieces 230 having the arc will be deformed to tightly clamp the hinged joint 130, thereby completing the connection of the grouting nail 120 and the tallow head 200.

[0052] When the grouting machine body 100 is normally working, since the grouting pipe 110 and the tallow head 200 are connected together and the grouting nail 120 has a certain height on the wall surface, the grouting pipe 110 will be sagged at the connection position of the tallow head 200 and the grouting nail 120 under the action of gravity, causing the tallow head 200 to be inclined at the connection position with the grouting nail 120 under the action of gravity of the grouting pipe 110, and the vibration generated when the grouting machine body 100 works will be transmitted to the tallow head 200 and the grouting nail 120 through the grouting pipe 110, thereby further affecting the sealing performance at the connection position of the tallow head 200 and the grouting nail 120.

[0053] Based on this, the shell 210 is axially elastically slidably connected with the claw sleeve 250 away from the grouting pipe 110, and the grouting nail 120 is provided with the clamping groove 140 near the hinged joint 130, the claw sleeve 250 can clamp the clamping groove 140 after clamping the hinged joint 130 by the elastic clamping pieces 230, so that the hinged joint 130 and the clamping groove 140 of the grouting nail 120 are clamped, and the connection position of the grouting nail 120 and the butter head 200 has two, compared with the prior art that only the hinged joint 130 is connected with the butter head 200, the two connection positions can improve the connection strength of the butter head 200 and the grouting nail 120, and reduce the influence of the gravity of the grouting pipe 110 on the connection of the butter head 200 and the grouting nail 120.

[0054] It can be understood that when only the hinged joint 130 of the grouting nail 120 is connected with the elastic clamping pieces 230 of the butter head 200, the connection position of the grouting nail 120 and the butter head 200 will be inclined, at this time, the clamping effect of the elastic clamping pieces 230 on the hinged joint 130 is poor, and the clamping groove 140 is arranged between the hinged joint 130 and the grouting nail 120, and the claw sleeve 250 is arranged on the shell 210 of the butter head 200, the claw sleeve 250 is clamped in the clamping groove 140 to clamp the grouting nail 120 again, and the elastic clamping pieces 230 are clamped on the hinged joint 130 at the same time, so that the connection position of the grouting nail 120 and the butter head 200 has two, at this time, the axis of the grouting nail 120 and the butter head 200 coincides, so that the connection position of the butter head 200 and the grouting nail 120 is avoided to be inclined, and the sealing property of the connection position of the butter head 200 and the grouting nail 120 is improved.

[0055] Specifically, as Figure 12As shown, the clamping jaw sleeve 250 in the application has a plurality of elastic clamping jaws at one end, the plurality of elastic clamping jaws have elasticity, and the diameter of the plurality of elastic clamping jaws is slightly smaller than the diameter of the clamping groove 140, so that the elastic clamping jaws can clamp the clamping groove 140 when located at the position of the clamping groove 140. The other end of the clamping jaw sleeve 250 is cylindrical. When the operator connects the butter head 200 and the grouting nail 120 together, the hinge joint 130 of the grouting nail 120 will abut against the clamping jaw sleeve 250. When the operator pushes the butter head 200, the clamping jaw sleeve 250 will elastically move axially. When the force of the operator pushing the butter is greater than the elastic moving force, the hinge joint 130 passes through the elastic clamping jaws of the clamping jaw sleeve 250, and the hinge joint 130 abuts against one end of the plurality of elastic clamping pieces 230 having an arc. The operator continues to exert force, so that the one end of the plurality of elastic clamping pieces 230 having an arc is deformed by the hinge joint 130. The hinge joint 130 is gradually clamped by the plurality of elastic clamping pieces 230, at the same time, the clamping jaw sleeve 250 moves axially relative to the hinge joint 130, and the clamping jaw sleeve 250 gradually approaches the clamping groove 140. When the hinge joint 130 is completely clamped and fixed by the plurality of elastic clamping pieces 230, the clamping jaw sleeve 250 is clamped in the clamping groove 140, thereby completing the connection of the butter head 200 and the grouting nail 120.

[0056] In further embodiments, due to the gravity of the grouting pipe 110, the force of the hinge joint 130 on the plurality of elastic clamping pieces 230 is different. If the position is not changed for a long time, the same elastic clamping piece 230 will continuously bear a larger force, which will cause the wear degree to increase and affect the service life. Therefore, in order to solve this problem, the plurality of elastic clamping pieces 230 are rotationally arranged, so that the position of the plurality of elastic clamping pieces 230 inside the butter head 200 will change every time the operator installs the butter head 200, thereby avoiding the situation that a certain elastic clamping piece 230 continuously bears force.

[0057] Specifically, the clamping ring 240 is in sliding connection with the plurality of elastic clamping pieces 230 in the peripheral direction, so that the clamping ring 240 and the plurality of elastic clamping pieces 230 cannot rotate relative to each other in the peripheral direction. The side wall of the clamping ring 240 is provided with a plurality of arc-shaped through grooves 241, and the plurality of elastic clamping pieces 230 are respectively arranged in the plurality of arc-shaped through grooves 241 in a sliding manner. A rotating sleeve 260 is arranged on the outer periphery of the clamping ring 240 in the axial direction. The outer periphery of the clamping ring 240 has a rectangular block 242. The inner periphery of the rotating sleeve 260 is provided with a sliding groove 261 extending in the axial direction. The rectangular block 242 is located in the sliding groove 261. The outer periphery of the rotating sleeve 260 is in rotating connection with the inner periphery of the clamping jaw sleeve 250. The rotating sleeve 260 can drive the clamping ring 240 to rotate around the axis thereof. When the clamping ring 240 rotates around the axis thereof, the plurality of elastic clamping pieces 230 can be driven to rotate synchronously, so that the positions of the plurality of elastic clamping pieces 230 change. It should be noted that the rotating sleeve 260 in the embodiment is configured to drive the rotating sleeve 260 to rotate around the axis thereof when the clamping jaw sleeve 250 moves in the axial direction, thereby driving the clamping ring 240 and the plurality of elastic clamping pieces 230 to rotate synchronously.

[0058] More specifically, to achieve the clamping jaw sleeve 250 driving the rotating sleeve 260 to rotate around the axis thereof when the clamping jaw sleeve 250 moves in the axial direction, as shown in the figure, Figure 10 the outer periphery of the rotating sleeve 260 in the embodiment is uniformly provided with a plurality of first sliding rails 270 extending in the axial direction. The second sliding rail 280 is arranged between adjacent first sliding rails 270. The second sliding rail 280 is helical, and the two ends of the second sliding rail 280 are respectively connected to the first end and the second end of adjacent first sliding rails 270. Three rails parallel to each other and extending in the axial direction of the rotating sleeve 260 are arranged in the first sliding rail 270. The two outer rails of the three rails are respectively connected to the second sliding rail 280. The middle rail of the three rails is respectively connected to the first end and the second end of the two outer rails, as shown in the figure, Figure 12 the inner periphery of the clamping jaw sleeve 250 in the embodiment is fixedly provided with a plurality of elastic protrusions 251. The elastic protrusions 251 can slide through the first sliding rail 270 and the second sliding rail 280. When the clamping jaw sleeve 250 moves in the axial direction, the clamping jaw sleeve 250 does not rotate in the peripheral direction, so that the elastic protrusions 251 inside the clamping jaw sleeve 250 slide in the second sliding rail 280. Since the second sliding rail 280 is helical and connected to the first end and the second end of adjacent first rails 271, the elastic protrusions 251 and the second sliding rail 280 drive the rotating sleeve 260 to rotate around the axis thereof.

[0059] As shown in the figure, Figure 10As shown, the three tracks inside the first slide rail 270 of the present invention have different depths, and the connection between the middle track and the two side tracks is achieved through a stepped surface (the stepped surface is stepped, so when the elastic protrusion 251 enters the lower end of the stepped surface, it moves to the next step and cannot return to the previous position). The stepped surface has an inclined surface, which allows the elastic protrusion 251 to move from one track to another. The depth of the three tracks gradually increases in a preset direction, for example, with... Figure 10 As shown, the depth of the three tracks gradually increases from left to right. The depth of the same second slide rail 280 is not the same everywhere, but gradually becomes shallower. For example, with... Figure 10 As shown, the second slide rail 280 gradually becomes shallower from left to right, so that the elastic protrusion 251 can pass through the second slide rail 280 into the shallowest track of the first slide rail 270 from the deepest track in the first slide rail 270.

[0060] For ease of description, Figure 10 The three tracks shown, from left to right, are named first track 271, second track 272, and third track 273, respectively. The elastic protrusion 251 inside the gripper sleeve 250 is initially located within the deepest track of the first track 270, which is the third track 273. Figure 10 As shown, when the gripper sleeve 250... Figure 10When the rotating sleeve 260 is moved in the arrow direction, the elastic protrusions 251 inside the clamping sleeve 250 are moved from the third track 273 inside the first slide rail 270 to the second slide rail 280, so that the rotating sleeve 260 rotates around its axis, and when the elastic protrusions 251 move to the end of the other first slide rail 270, the clamping sleeve 250 has been clamped in the clamping groove 140, and when the operator releases his hand, the elastic protrusions 251 inside the clamping sleeve 250 slide into the connecting position of the first track 271 and the second track 272, and pass over the step surface at the connecting position of the first track 271 and the second track 272, at this time, the rotating sleeve 260 does not rotate, and when it is necessary to disassemble the butter head 200, the operator needs to push the clamping sleeve 250 so that the clamping sleeve 250 is separated from the clamping groove 140, at this time, the elastic protrusions 251 inside the clamping sleeve 250 enter the second track 272 under the action of the inclined surface of the step surface, and slide along the second track 272 to the connecting position of the second track 272 and the third track 273, and the elastic protrusions 251 pass over the step surface at the connecting position of the second track 272 and the third track 273, when the clamping sleeve 250 is separated from the clamping groove 140, the operator releases the pushing of the clamping sleeve 250, so that the clamping sleeve 250 resets to drive the elastic protrusions 251 inside the inner circumference to move in the third track 273 and to the connecting position of the third track 273 and the second slide rail 280. When the butter head 200 is connected again, the rotating sleeve 260 still rotates clockwise, and the specific process is the same as described above, and will not be described in detail.

[0061] In a further embodiment, the clamping sleeve 250 of the present application is provided with an adjusting assembly, which can adjust the distance between the clamping ring 240 and the hinge joint 130 when the clamping ring 240 is in the initial position, and when the distance between the clamping ring 240 and the hinge joint 130 is closer, the position of the clamping ring 240 is closer to the end of the plurality of elastic clamping pieces 230 having an arc, so that the clamping force of the plurality of elastic clamping pieces 230 on the hinge joint 130 is increased. It should be noted that the elastic clamping pieces 230 in the present embodiment are arranged as shown in Figure 5 and Figure 11 The end of the plurality of elastic clamping pieces 230 having an arc is suspended, and there is a gap between adjacent elastic clamping pieces 230, which provides space for the deformation of the elastic clamping pieces 230, and when the clamping ring 240 slides on the plurality of elastic clamping pieces 230, the length of the force arm of the elastic clamping pieces 230 when clamping the hinge joint 130 can be changed, as shown in Figure 5As shown, when the clamping ring 240 moves to the left, the length of the force arm of the plurality of elastic clamping pieces 230 clamping the articulated joint 130 is shortened, the difficulty of deformation of the plurality of elastic clamping pieces 230 is increased, so that the clamping force of the plurality of elastic clamping pieces 230 on the articulated joint 130 is increased, when the clamping ring 240 moves to the right, the length of the force arm of the plurality of elastic clamping pieces 230 clamping the articulated joint 130 is increased, the difficulty of deformation of the plurality of elastic clamping pieces 230 is reduced, so that the clamping force of the plurality of elastic clamping pieces 230 on the articulated joint 130 is reduced.

[0062] It should be noted that the grouting nail 120 and the tallow head 200 in the present application are installed and disassembled multiple times, which can cause the plurality of elastic clamping pieces 230 inside the tallow head 200 to fatigue and deform at the position close to the end with the arc, thereby affecting the clamping force of the plurality of elastic clamping pieces 230 on the articulated joint 130, therefore, the adjusting assembly in the present embodiment can adjust the position of the clamping ring 240 to reduce the influence of fatigue deformation.

[0063] Specifically, the adjusting assembly in the present embodiment includes a sliding block 300, an adjusting rod 310 and a limiting block 330, as shown in the figure. Figure 12 As shown, the sliding block 300 is circumferentially slidably arranged in the inner circumference of the clamping jaw sleeve 250, for easy connection, a rotating ring groove 252 is arranged in the inner circumference of the clamping jaw sleeve 250, the sliding block 300 is arranged in the rotating ring groove 252, the sliding block 300 can move along the rotating ring groove 252, the adjusting rod 310 axially slides through the sliding block 300, a rectangular through groove is formed on the sliding block 300, the cross section of the adjusting rod 310 is rectangular, one end of the adjusting rod 310 is fixedly connected to the clamping ring 240, when the adjusting rod 310 moves relative to the sliding block 300, the distance between the clamping ring 240 and the articulated joint 130 at the initial position can be adjusted.

[0064] It should be noted that when the operator connects the tallow head 200 and the grouting nail 120 together, the articulated joint 130 of the grouting nail 120 pushes the clamping jaw sleeve 250, the rotating ring groove 252 inside the clamping jaw sleeve 250 drives the sliding block 300 to move synchronously, thereby making the sliding block 300 drive the adjusting rod 310 to move axially, the adjusting rod 310 drives the clamping ring 240 to move away from the articulated joint 130, at this time, the difficulty of deformation of the plurality of elastic clamping pieces 230 is reduced, thereby facilitating the articulated joint 130 to enter the inside of the end of the plurality of elastic clamping pieces 230 with the arc, when the plurality of elastic clamping pieces 230 clamps the articulated joint 130, the clamping jaw sleeve 250 resets, the clamping jaw sleeve 250 drives the rotating ring groove 252 to reset, thereby making the rotating ring groove 252 drive the sliding block 300 and the adjusting rod 310 to move synchronously, the adjusting rod 310 pulls the clamping ring 240 to return to the initial position, thereby restoring the difficulty of deformation of the plurality of elastic clamping pieces 230.

[0065] When the clamping force of the plurality of elastic clamping pieces 230 on the hinge joint 130 needs to be adjusted, the operator can adjust the position of the adjusting rod 310 inside the sliding block 300 by adjusting the limiting block 330, thereby adjusting the position of the clamping ring 240 from the initial position to the position of the hinge joint 130. For example, when the clamping force of the plurality of elastic clamping pieces 230 on the hinge joint 130 needs to be increased, the limiting block 330 is first loosened, and then the adjusting rod 310 is pulled to move so that the elastic clamping piece 230 is closer to the hinge joint 130; when the clamping force of the plurality of elastic clamping pieces 230 on the hinge joint 130 needs to be reduced, the limiting block 330 is first loosened, and then the adjusting rod 310 is pushed to move so that the elastic clamping piece 230 is farther away from the hinge joint 130.

[0066] Specifically, the limiting block 330 in the embodiment is hinged at one end on the sliding block 300 and abuts at the other end on the adjusting rod 310. The adjusting rod 310 is provided with a plurality of limiting teeth 320, and the limiting block 330 is also provided with limiting teeth 320. A torsional spring (not shown in the figure) is arranged at the hinged position. The torsional spring tightly abuts the plurality of limiting blocks 330 on the adjusting rod 310, so that the limiting teeth 320 on the limiting block 330 and the limiting teeth 320 on the adjusting rod 310 are engaged, thereby limiting the adjusting rod 310 inside the sliding block 300. When adjustment is needed, the operator rotates the limiting block 330 around the hinged position against the action force of the torsional spring, so that the limiting teeth 320 of the limiting block 330 and the limiting teeth 320 of the adjusting rod 310 are disengaged, thereby adjusting the position of the adjusting rod 310 inside the sliding block 300.

[0067] It can be understood that as the number of disassembly of the butter head 200 increases, the end of the plurality of elastic clamping pieces 230 with an arc will be normally worn, thereby reducing the service life of the elastic clamping piece 230. Therefore, the elastic clamping piece 230 has an arc at both ends. When one end is worn to a greater extent, the two ends of the elastic clamping piece 230 can be exchanged, so that the unworn end is used, thereby prolonging the service life of the elastic clamping piece 230.

[0068] Specifically, in order to facilitate the elastic clamping piece 230 with an arc at both ends to be installed on the outer periphery of the ventilation sleeve 220, the present application coaxially and slidably provides a connecting sleeve 290 on the outer periphery of the ventilation sleeve 220. The outer periphery of the connecting sleeve 290 also has an arc, thereby being able to adapt to the plurality of elastic clamping pieces 230, so that the inner side of the plurality of elastic clamping pieces 230 is fitted on the outer periphery of the connecting sleeve 290.

[0069] In a further embodiment, the housing 210 in the embodiment of the present application is provided with a first elastic member 410, one end of the first elastic member 410 is connected to the inner wall of the housing 210, the other end of the first elastic member 410 is connected to one end of the vent sleeve 220, and a gasket 430 is arranged at both ends of the first elastic member 410, the arrangement of the gasket 430 can reduce the wear of the first elastic member 410 to the inside of the housing 210 and the vent sleeve 220, and at the same time, the gasket 430 has a through hole, which allows the slurry to flow.

[0070] More specifically, the second elastic member 420 is arranged between the housing 210 and the jaw sleeve 250 in the embodiment, one end of the second elastic member 420 is connected to the housing 210, the other end of the second elastic member 420 is connected to the jaw sleeve 250, at the same time, a plurality of guide rods 253 are arranged on the end of the jaw sleeve 250 close to the housing 210, and a guide hole 211 extending along the axial direction is arranged on the side wall of the jaw sleeve 250, the guide rod 253 is slidingly inserted into the guide hole 211, so that the jaw sleeve 250 can elastically slide axially on the housing 210.

[0071] It should be noted that the first elastic member 410 and the second elastic member 420 in the embodiment are both compression springs, and a limiting sleeve 400 is threadedly connected to the end of the housing 210 connecting the jaw sleeve 250, a limiting groove 401 is arranged on the inner periphery of the limiting sleeve 400, and a limiting ring 254 is arranged on the outer periphery of the jaw sleeve 250, the limiting ring 254 can axially slide in the limiting groove 401, so as to avoid the jaw sleeve 250 from being separated from the housing 210.

[0072] The specific working process of the basement waterproof construction device provided by the present application is described in combination with the above embodiments:

[0073] Install the grouting nail 120 and the butter head 200:

[0074] The operator needs to install the grouting nail 120 on the wall body which needs waterproof construction, the grouting nail 120 is perpendicular to the wall body, then the grouting pipe 110 of the grouting machine body 100 is connected on the grouting nail 120, so that the slurry in the grouting machine body 100 enters into the wall body through the grouting pipe 110 and the grouting nail 120, the butter head 200 is connected on the grouting pipe 110, the clamping jaw sleeve 250 is axially elastically slidably arranged on the shell 210 of the butter head 200, the operator holds the butter head 200 and pushes the butter head 200 to move towards the direction of the grouting nail 120, the clamping jaw sleeve 250 will first abut against the hinge joint 130 of the grouting nail 120, then when the operator exerts force, the hinge joint 130 of the grouting nail 120 gradually enters into the clamping jaw sleeve 250, and the clamping jaw sleeve 250 will extrude the second elastic member 420, when the clamping jaw sleeve 250 moves, the sliding block 300 and the limiting block 330 drive the adjusting rod 310 to move, the adjusting rod 310 drives the clamping ring 240 to move, the clamping ring 240 moves away from the direction of the hinge joint 130, at the same time, since the clamping jaw sleeve 250 will have the effect of clamping the hinge joint 130 after deformation, the clamping jaw sleeve 250 will not rotate when moving axially, the elastic protrusions 251 on the inner wall of the clamping jaw sleeve 250 will slide in the second sliding rails 280 of the rotating sleeve 260 to drive the clamping ring 240 to rotate, the clamping ring 240 drives the plurality of elastic clamping pieces 230 to synchronously rotate, so that the positions of the plurality of elastic clamping rings 240 change.

[0075] When the hinge joint 130 gradually moves to contact the plurality of elastic clamping pieces 230 and gradually enters the inside of the end with the arc of the plurality of elastic clamping pieces 230, when the hinge joint 130 is clamped by the plurality of elastic clamping pieces 230, the clamping jaw sleeve 250 also gradually resets to be clamped in the clamping groove 140, at this time, the clamping jaw sleeve 250 can drive the clamping ring 240 to reset synchronously when resetting, so that the clamping ring 240 is close to the hinge joint 130, thereby ensuring that the plurality of elastic clamping pieces 230 can tightly clamp the hinge joint 130.

[0076] As the use time of the butter head 200 increases, the plurality of elastic clamping pieces 230 close to the position with the arc end will be fatigue deformed due to multiple installation and disassembly, resulting in the clamping force of the plurality of elastic clamping pieces 230 decreasing, therefore the limiting block 330 can be actuated to release the limitation of the limiting block 330 on the adjusting rod 310, the operator pulls the adjusting rod 310 to change the position of the clamping ring 240 on the plurality of elastic clamping pieces 230, so that the clamping ring 240 is closer to the hinge joint 130 to cover the position of fatigue deformation, thereby enhancing the clamping force of the plurality of elastic clamping pieces 230 to avoid the hinge joint 130 from being separated.

[0077] If the wear degree of one end of the plurality of elastic clamping pieces 230 is large, the positions of the two ends of the plurality of elastic clamping pieces 230 can be exchanged, thereby prolonging the service life of the elastic clamping pieces 230.

[0078] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered to be within the scope of the present disclosure.

[0079] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
