Description

Technical fields:

[0001] This invention belongs to the field of construction equipment technology, specifically a tool clamp quick installation and removal device. Background technology:

[0002] Traditional 55-hole tensioning jacks require 55 tool clamps to be installed sequentially on 55 conical holes for tensioning operations. These clamps tightly hold the steel strand to achieve tensioning. This process is manual, time-consuming, labor-intensive, and inefficient. Furthermore, after installation, some tool clamps may fall off or slip due to poor installation quality, severely impacting the construction progress. Based on these findings, this invention provides a quick-installation and removal device for tool clamps. This device allows multiple tool clamps to be installed into the conical holes of the tool anchor plate at once, enabling rapid installation and removal and improving construction efficiency. Summary of the Invention:

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a tool clip quick installation and removal device.

[0004] The present invention adopts the following technical solution:

[0005] A quick-release device for tool clamps includes a tool anchor plate, an integrated pressure plate, tool clamps, and a driving device. The tool anchor plate has several conical holes, and the number of tool clamps matches the number of conical holes, distributed within each conical hole. The integrated pressure plate is positioned above the tool anchor plate and has through holes matching the number of conical holes, with each through hole corresponding to one of the conical holes. The integrated pressure plate is connected to the tool clamps via a connecting device. The driving device is mounted on the tool anchor plate and connected to the integrated pressure plate, driving the integrated pressure plate to move towards or away from the tool anchor plate. During installation, the driving device moves the integrated pressure plate towards the tool anchor plate, thereby moving the tool clamps into the conical holes, tightening them, and firmly clamping the steel strand inside the tool clamps. During disassembly, the driving device moves the integrated pressure plate away from the tool anchor plate, thereby moving the tool clamps away from the conical holes, loosening them, and completing the disassembly of the tool clamps.

[0006] Furthermore, the connecting device includes bolt fasteners with the same number of tool clips, and each set of bolt fasteners includes three clip fixing screws; three through holes are evenly distributed circumferentially next to each through hole of the integrated pressure plate, the inner diameter of the through holes is adapted to the size of the clip fixing screws, and the lower end of the clip fixing screws passes through the through holes and is fixedly connected to the tool clips.

[0007] Furthermore, the lower end of the clamp fixing screw is provided with an external thread, and correspondingly, the tool clamp is provided with a threaded hole, and the clamp fixing screw is threadedly fixed to the tool clamp.

[0008] Furthermore, the diameter of the nut of the clamp fixing screw is larger than the inner diameter of the through hole; the clamp fixing screw is movably connected to the integrated pressure plate, and the integrated pressure plate can move relative to the clamp fixing screw.

[0009] Furthermore, a pressure plate moving guide device is also provided, which includes several sets of guide bolts. The integrated pressure plate has guide holes with the same number of guide bolts. The inner diameter of the guide holes is adapted to the size of the guide bolts. The lower end of the guide bolts passes through the guide holes on the integrated pressure plate and is fixedly connected to the tool anchor plate.

[0010] Furthermore, the diameter of the nut of the guide bolt is larger than the inner diameter of the guide hole; the guide bolt is movably connected to the integrated pressure plate, and the integrated pressure plate can move relative to the guide bolt.

[0011] Furthermore, the guide bolts are provided in three sets, distributed on the outer edge of the integrated pressure plate, with the distance between adjacent sets of guide bolts being the same.

[0012] Furthermore, the driving device includes a mounting base, a ratchet wrench, a connecting rod, and a shift fork; the mounting base is fixedly mounted on the tool anchor plate, the connecting rod is rotatably mounted on the mounting base, the ratchet wrench is drivenly connected to the connecting rod, both ends of the connecting rod are fixedly connected to the shift fork, and the shift fork is hinged to the integrated pressure plate; the ratchet wrench drives the connecting rod to rotate, causing the shift fork to rotate around the connection point between the connecting rod and the shift fork, thereby driving the integrated pressure plate to move in a direction closer to or away from the tool anchor plate, thereby realizing the installation or removal of the tool clamp.

[0013] Furthermore, the integrated pressure plate is provided with two sets of handles, which are fixedly installed on the integrated pressure plate, and the two sets of handles are symmetrically distributed at both ends of the integrated pressure plate.

[0014] Furthermore, the tool anchor plate has 55 tapered holes, and correspondingly, the tool clamping pieces have 55 pieces.

[0015] The beneficial effects of this invention are:

[0017] (2) This device is equipped with three sets of guide bolts as a guide device for moving the pressure plate. The guide bolts are movably connected to the integrated pressure plate, so that the integrated pressure plate can only move along the axis of the guide bolts, thus avoiding deviation during the movement.

[0018] (3) The integrated pressure plate set in this device can press the tool clip into the conical hole of the tool anchor plate to complete the installation of the tool clip, and can also prevent the tool clip from falling off during the application process and affecting the construction operation.

[0019] (4) This device solves the problems of low efficiency and easy falling off caused by the traditional manual installation of tool clamps one by one. It enables tool clamps to be installed and removed quickly, and the construction method is simple to operate. The construction quality and safety are easy to control. It is suitable for the installation and disassembly of tool clamps of 55-hole large-tonnage prestressed tensioning jacks in the process of clamping steel strands. It is highly practical.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] Example 1

[0031] Reference Figures 1-3 This invention provides a tool clamp quick installation and removal device, including a tool anchor plate 1, an integrated pressure plate 3, tool clamps 2, and a driving device; the tool anchor plate 1 is provided with 55 conical holes, and the number of tool clamps 2 is the same as the number of conical holes, distributed in each conical hole.

[0032] The integrated pressure plate 3 is positioned above the tool anchor plate 1. The integrated pressure plate 3 has 55 through holes, each corresponding to a conical hole. The inner diameter of the through holes is smaller than that of the conical holes to prevent the tool clamping piece 2 from entering the through holes of the integrated pressure plate 3. The integrated pressure plate 3 is connected to the tool clamping piece 2 via a connecting device. The driving device is mounted on the tool anchor plate 1 and connected to the integrated pressure plate 3, enabling the integrated pressure plate 3 to move towards or away from the tool anchor plate 1. The structure of the tool clamping piece 2 is an existing structure and will not be described in detail here.

[0033] In this embodiment, the integrated pressure plate 3 is provided with two sets of handles 6, which are fixedly installed on the integrated pressure plate 3, and the two sets of handles 6 are symmetrically distributed at both ends of the integrated pressure plate 3.

[0034] When the tool clamp 2 is installed, the drive device moves the integrated pressure plate 3 toward the tool anchor plate 1. The integrated pressure plate 3 exerts pressure on the tool clamp 2, thereby driving the tool clamp 2 into the conical hole, making the tool clamp 2 tighten, and the steel strand is tightly clamped inside the tool clamp 2. When the tool clamp 2 is removed, the drive device moves the integrated pressure plate 3 away from the tool anchor plate 1, thereby driving the tool clamp 2 away from the conical hole, making the tool clamp 2 loose, and completing the removal of the tool clamp 2.

[0035] Example 2

[0036] The main structure of this embodiment is the same as that of embodiment 1. The difference is that this embodiment defines the specific structure of the connecting device.

[0037] Specifically, refer to Figures 1-2In this embodiment, the connecting device includes 55 sets of bolt fasteners, each set of bolt fasteners including three clamping screws 4; three through holes are circumferentially and equidistantly distributed next to each through hole of the integrated pressure plate 3, the inner diameter of the through holes being adapted to the size of the clamping screws 4, and the lower end of the clamping screws 4 passing through the through holes and fixedly connected to the tool clamp 2. The nut diameter of the clamping screws 4 is larger than the inner diameter of the through holes, and the clamping screws 4 are movably connected to the integrated pressure plate 3, allowing the integrated pressure plate 3 to move relative to the clamping screws 4.

[0038] In this embodiment, the lower end of the clamp fixing screw 4 is provided with an external thread, and correspondingly, the tool clamp 2 is provided with a threaded hole, and the clamp fixing screw 4 is threadedly fixedly connected to the tool clamp 2.

[0039] In this embodiment, the clamp fixing screw 4 can, on the one hand, connect the integrated pressure plate 3 and the tool clamp 2 movably, and on the other hand, guide the movement of the integrated pressure plate 3, so that the integrated pressure plate 3 always moves along the axial direction of the clamp fixing screw 4, and avoids deviation during the movement.

[0040] Example 3

[0041] The main structure of this embodiment is the same as that of embodiment 2. The difference is that in this embodiment, a pressure plate moving guide device is also provided, which can further prevent the integrated pressure plate 3 from shifting.

[0042] Specifically, refer to Figures 1-3 In this embodiment, the pressure plate moving guide device includes three sets of guide bolts 5. The outer edge of the integrated pressure plate 3 is provided with three guide holes at equal intervals. The inner diameter of the guide holes is adapted to the size of the guide bolts 5. The lower end of the guide bolts 5 passes through the guide holes on the integrated pressure plate 3 and is fixedly connected to the tool anchor plate 1.

[0043] In this embodiment, the nut diameter of the guide bolt 5 is larger than the inner diameter of the guide hole; the guide bolt 5 is movably connected to the integrated pressure plate 3, and the integrated pressure plate 3 can move relative to the guide bolt 5. The integrated pressure plate 3 can only move along the bolt axis to avoid deviation.

[0044] Example 4

[0045] The main structure of this embodiment is the same as that of embodiment 3. The difference is that this embodiment defines the specific structure of the driving device.

[0046] Specifically, refer to Figure 1In this embodiment, the driving device includes a mounting base 10, a ratchet wrench 7, a connecting rod 9, and a shift fork 8. The mounting base 10 is fixedly mounted on the tool anchor plate 1, the connecting rod 9 is rotatably mounted on the mounting base 10, the ratchet wrench 7 is drivenly connected to the connecting rod 9, the two ends of the connecting rod 9 are fixedly connected to the shift fork 8, and the shift fork 8 is hinged to the integrated pressure plate 3.

[0047] In application, the ratchet wrench 7 drives the linkage 9 to rotate, causing the shift fork 8 to rotate around the connection point between the linkage 9 and the shift fork 8, thereby driving the integrated pressure plate 3 to move in a direction close to or away from the tool anchor plate 1, so that the tool clamp 2 is pressed into the conical hole or leaves the conical hole, realizing the installation or removal of the tool clamp 2.

[0048] Specifically, the application method of this device includes the following steps:

[0049] Step 1, according to Figure 1 The quick-assembly / disassembly device is now assembled.

[0050] The second step is to adjust the direction of the ratchet wrench and continuously apply force to make the integrated pressure plate a certain distance away from the tool anchor plate, so that the tool clamping plate opens. Pass the steel strand through the through hole on the integrated pressure plate and the tapered hole on the tool anchor plate, and clamp it into the tool clamping plate.

[0051] The third step is to adjust the direction of the ratchet wrench and continuously apply force to reduce the distance between the integrated pressure plate and the tool anchor plate, and drive the tool clamping plate into the tapered hole on the tool anchor plate, so that the tool clamping plate tightly clamps the steel strand.

[0052] Step 4: Start the tensioning jack to move the tool anchor plate, while the steel strand is tightly clamped by the tool clamping plate to generate tension.

[0053] Step 5: After the steel strand is securely anchored, adjust the direction of the ratchet wrench and continuously apply force to make the tool clamp integrated pressure plate a certain distance away from the tool anchor plate, so that the tool clamp opens and the tool clamp is disassembled.
