Description

Technical Field

[0001] This utility model relates to the technical field of drainage board insertion equipment, and in particular to a drainage board guide tube telescopic device. Background Technology

[0002] The measures to solidify weak sites or foundations usually adopt drainage solidification schemes. Typically, drainage board insertion equipment is used to drive drainage boards into the site or foundation. The drainage board is a guide plate with internal channels. After the drainage board construction is completed, a vacuum and pressure reduction facility is built on the ground. By vacuuming and depressurizing, the water in the site or foundation rises along the drainage board to the ground and is collected and discharged, thereby greatly reducing the moisture content of the site or foundation.

[0003] Currently, the installation of drainage boards requires the erection of a pile frame. The entire guide pipe of the drainage board is erected on the pile frame to guide the drainage board into the ground. When the construction site has height restrictions, such as near an airport or under a bridge, the height of the pile frame cannot exceed the maximum height restriction, which means that a single guide pipe cannot drive the drainage board to the preset depth. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a drainage board conduit telescopic device that uses a telescopic conduit to drive the drainage board into a preset depth within the height limit requirement.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a frame, an insert plate driving device disposed at the bottom of the frame, and a transmission chain disposed on the frame for transmitting torque; it also includes an insert connector, an inner insert, an outer insert, and two sets of limiting members. The insert connector is fixedly connected to the transmission chain, the inner insert is fixedly connected to the middle of the insert connector, the outer insert is slidably connected to the outside of the inner insert, and the two sets of limiting members are detachably connected to the upper edge of the outer wall of the outer insert, with each limiting member passing through the outer insert and engaging with the inner insert in a limiting cooperation.

[0006] Furthermore, each end of the inner tube is provided with at least two upper limit grooves and at least two lower limit grooves, with a plurality of the upper limit grooves disposed on the upper part of the inner tube and a plurality of the lower limit grooves disposed on the lower part of the inner tube.

[0007] Furthermore, several upper limit slots and several lower limit slots are staggered in the inner tube.

[0008] Furthermore, the upper part of the external insertion tube is provided with two second limiting grooves, each of which corresponds to a guiding engagement with the corresponding limiting member.

[0009] Furthermore, the two second limiting slots are arranged alternately.

[0010] Furthermore, the length of the external insertion tube is shorter than the length of the internal insertion tube.

[0011] Furthermore, the limiting member includes two clamping members fixedly connected to the outer insertion tube, a pressure block disposed between the two clamping members, and a lifting member disposed at the end of the pressure block. Each clamping member is provided with a spring piece, the other end of which is connected to the pressure block. The pressure block passes through the outer insertion tube and engages with the inner insertion tube for limiting.

[0012] Furthermore, a mounting box is provided at the bottom of the frame, the insert plate drive device is fixedly connected to the mounting box, a driven wheel is provided at the top of the frame, the transmission chain is wound around the driven wheel and the insert plate drive device in sequence, and an anti-jump tooth for preventing jumping is pivotally connected above the mounting box, the anti-jump tooth meshing with the transmission chain.

[0013] The beneficial effects of this utility model are: by adopting a nested outer tube and inner tube structure, under strict height restriction conditions, the splicing of the outer tube and inner tube can be realized through a detachable limiting component. The drainage board is inserted to a predetermined depth in a segmented insertion manner under the height restriction condition of the frame. The overall structure is lightweight. When using it, only the lifting component needs to be pulled to unlock it. When locking, the elasticity of the spring plate makes the pressure block fall into place automatically, which improves the convenience of locking. Attached Figure Description

[0022] like Figures 1 to 2 As shown, in this embodiment, the present invention includes a frame 1, an insert plate driving device 2 disposed at the bottom of the frame 1, and a transmission chain 3 disposed on the frame 1 for transmitting torque; it also includes an insert connector 4, an inner insert tube 5, an outer insert tube 6, and two sets of limiting members 7. The insert connector 4 is fixedly connected to the transmission chain 3, the inner insert tube 5 is fixedly connected to the middle of the insert connector 4, the outer insert tube 6 is slidably connected to the outside of the inner insert tube 5, and the two sets of limiting members 7 are detachably connected to the upper edge of the outer wall of the outer insert tube 6. Each limiting member 7 passes through the outer insert tube 6 and engages with the inner insert tube 5 for limiting.

[0023] Specifically, both the inner tube 5 and the outer tube 6 are hollow structures. The middle of the inner tube 5 and the outer tube 6 allows the drainage plate to pass through. The bottom of the outer tube 6 is connected to a boot cap for the drainage plate to be driven in. The insertion plate drive device 2 is a double-drum winch housing. The movable end of the insertion plate drive device 2 is equipped with a drive wheel with 30 teeth. The drive wheel meshes with the transmission chain 3 to output kinetic energy. There are two sets of insertion plate drive devices 2 and transmission chains 3. The insertion plate drive devices 2 and transmission chains 3 are symmetrically arranged on the frame 1. The two sides of the insertion tube joint 4 are fixedly connected to the two transmission chains 3. The two transmission chains 3 drive the insertion tube joint 4 to move up and down. The limiting member 7 is controlled by the spring of the spring piece 74. The force presses the pressure block 72 into the first limiting groove 51 and the second limiting groove 61, so that the inner insertion tube 5 and the outer insertion tube 6 will not move relative to each other. Under the drive of the insertion plate drive device 2, the inner insertion tube 5 and the outer insertion tube 6 are simultaneously inserted into the soft soil foundation. After descending to the lower limit position, the limiting piece 7 is pulled up to unlock the inner insertion tube 5 and the outer insertion tube 6. The insertion plate drive device 2 drives in the opposite direction to pull up the inner insertion tube 5. When it reaches the first limiting groove 51 below the inner insertion tube 5, the pressure block 72 is automatically pressed into the first limiting groove 51 under the elastic force of the spring piece 74, automatically locking the inner insertion tube 5 and the outer insertion tube 6. At this time, the insertion plate drive device 2 can drive again to continue inserting the inner insertion tube 5 and the outer insertion tube 6.

[0024] The structure adopts a nested outer tube 6 and inner tube 5. Under strict height restriction conditions, the outer tube 6 and inner tube 5 can be spliced ​​through the detachable limiting part 7. The drainage board is inserted to the predetermined depth in a segmented insertion manner under the height restriction of the frame 1. The overall structure is lightweight. When using it, you only need to pull the lifting part 73 to unlock it. When locking, the elasticity of the spring piece 74 makes the pressure block 72 fall into place automatically, which improves the convenience of locking.

[0025] like Figure 4 As shown, in this embodiment, each end of the inner tube 5 is provided with at least two upper limit grooves 51 and at least two lower limit grooves 52. A plurality of the upper limit grooves 51 are provided on the upper part of the inner tube 5, and a plurality of the lower limit grooves 52 are provided on the lower part of the inner tube 5.

[0026] Specifically, the upper limit groove 51 and the lower limit groove 52 are both guided and cooperate with the pressure block 72. The upper limit groove 51 is set at the upper part of the inner tube 5, and the lower limit groove 52 is set at the lower part of the inner tube 5, so as to cooperate with the limit block to adjust the position of the outer tube 6 and lock it in place.

[0027] In this embodiment, several upper limit slots 51 and several lower limit slots 52 are staggered in the inner tube 5.

[0028] Specifically, the upper limit groove 51 and the lower limit groove 52 are staggered. By moving the inner tube up and down, the upper and lower limit grooves cooperate with the second limit groove 61 of the outer tube (pressed by the pressure block 72) to increase the insertion plate stroke and increase the insertion plate depth.

[0029] like Figure 5 As shown, in this embodiment, the upper part of the external insertion tube 6 is provided with two second limiting grooves 61, and each second limiting groove 61 corresponds to the corresponding limiting member 7 for guiding cooperation.

[0030] Specifically, the second limiting groove 61 is located on the upper part of the external insertion tube 6, which facilitates the staff to adjust and connect the internal insertion tube 5 and the external insertion tube 6.

[0031] In this embodiment, the two second limiting grooves 61 are staggered.

[0032] Specifically, the two staggered second limiting grooves 61 prevent the two pressure blocks 72, which are located at the same height, from extending too far into the drain plate and squeezing it, thus preventing damage to the drain plate.

[0033] In this embodiment, the length of the external insertion tube 6 is less than the length of the internal insertion tube 5.

[0034] like Figure 3 As shown, in this embodiment, the limiting member 7 includes two clamping members 71 fixedly connected to the external insertion tube 6, a pressure block 72 disposed between the two clamping members 71, and a lifting member 73 disposed at the end of the pressure block 72. Each clamping member 71 is provided with a spring piece 74, and the other end of the spring piece 74 is connected to the pressure block 72. The pressure block 72 passes through the external insertion tube 6 and is limited and engaged with the internal insertion tube 5.

[0035] Specifically, the spring 74 is a metal spring 74, one end of which is fixedly connected to the clamping member 71, and the other end of which is connected to the pressure block 72. It is used to apply pressure to the pressure block 72 so that the pressure block 72 is automatically pressed into the first limiting groove 51 and the second limiting groove 61. The clamping member 71 is a clamping screw, which is locked and fixed to the outer wall of the outer insertion tube 6. The lifting member 73 is a lifting screw, wherein the lifting member 73 forms a "T"-shaped handle for easy pulling by the staff.

[0036] like Figure 6 As shown, in this embodiment, a mounting box 11 is provided at the bottom of the frame 1, the insert plate drive device 2 is fixedly connected to the mounting box 11, a driven wheel 12 is provided at the upper part of the frame 1, the transmission chain 3 is wound around the driven wheel 12 and the insert plate drive device 2 in sequence, and an anti-jump tooth 13 for preventing jumping is pivotally connected above the mounting box 11, the anti-jump tooth 13 meshing with the transmission chain 3.

[0037] Specifically, the mounting box 11 is a sprocket box. The mounting box 11 is used to fix the insert plate drive device 2. It is set at the bottom of the frame 1 and drives the transmission chain 3 to rotate from below. The driven wheel 12 is a 19-tooth tensioning gear. It is set at the upper part of the frame 1 and is used to tension and fix the transmission chain 3. There are two anti-skid teeth 13, which are symmetrically arranged on the frame 1. They are used to press the transmission chain 3 inward, so that the transmission chain 3 is tensioned and the transmission chain 3 is reduced from falling off due to irregular jumping.

[0038] The working principle of this utility model:

[0039] Before insertion, the insertion connector 4 is located on the upper part of the frame 1, and the limiting member 7 locks the outer insertion tube 6 on the inner insertion tube 5. At this time, the limiting member 7 and the upper first limiting groove 51 of the inner insertion tube 5 are limited and locked.

[0040] During insertion, the inner tube 5 and the outer tube 6 are simultaneously inserted into the soft soil foundation under the drive of the insertion plate drive device 2. After the insertion tube connector 4 descends to the lower limit position, the limiting piece 7 is pulled up to unlock the inner tube 5 and the outer tube 6. The insertion plate drive device 2 drives in the opposite direction to pull up the inner tube 5. When it reaches the first limiting groove 51 below the inner tube 5, the pressure block 72 is automatically pressed into the first limiting groove 51 under the elastic force of the spring piece 74, automatically locking the inner tube 5 and the outer tube 6. At this time, the insertion plate drive device 2 can drive again to continue inserting the inner tube 5 and the outer tube 6, completing the insertion construction of one drainage board.

[0041] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
