Description

Technical Field

[0001] This application relates to the field of ladder technology, and in particular to a pre-embedded ladder support fixing device. Background Technology

[0002] Currently, in the construction process, the installation of ladders plays a key role in ensuring construction safety and improving construction efficiency. Ladders are fixed to the building wall by overlapping with long screws.

[0003] However, the method of fixing the ladder to the wall with long screws results in poor stability during actual operation, posing a safety hazard. Therefore, developing a new ladder fixing device with high stability performance has extremely important application value and practical significance for promoting the safe and efficient development of the construction industry. Utility Model Content

[0004] To improve the stability of ladders during use, this application provides a pre-embedded ladder support fixing device.

[0005] This application provides a pre-embedded ladder support fixing device, which adopts the following technical solution: An embedded ladder support fixing device includes a connecting base plate pre-installed on a wall and a detachable ladder. The connecting base plate is provided with a clamping mechanism for clamping and fixing the ladder and a support mechanism for enhancing the stability of the ladder.

[0006] By adopting the above technical solution, and utilizing the clamping mechanism and support mechanism on the connecting base plate, the support mechanism can enhance the stability of the ladder, and the clamping mechanism can further effectively clamp and fix the ladder, thereby improving the stability of the ladder during use, reducing safety hazards, ensuring construction safety, and also helping to improve construction efficiency.

[0007] Preferably, the clamping mechanism includes a connecting plate, a bidirectional lead screw, a drive motor for driving the bidirectional lead screw to rotate, and a clamping block for clamping the ladder. The connecting plate is disposed on the connecting base plate, the drive motor is disposed on the connecting plate, the output shaft of the drive motor is coaxially fixed with the bidirectional lead screw, two clamping blocks are provided, the two ends of the bidirectional lead screw are respectively threaded to the clamping blocks, and any one of the clamping blocks forms a sliding fit with the connecting base plate.

[0008] By adopting the above technical solution, the bidirectional lead screw is driven to rotate by a drive motor, and the clamping blocks at both ends of the bidirectional lead screw can move towards or away from each other on the bidirectional lead screw, thereby realizing the clamping or releasing operation of the ladder.

[0009] Preferably, any of the clamping blocks is provided with a sliding block, and the connecting base plate is provided with a sliding groove, wherein the sliding block and the sliding groove form a sliding engagement.

[0010] By adopting the above technical solution, the sliding block and the sliding groove form a sliding fit, making the sliding of the clamping block on the connecting plate more stable and smooth, reducing the possibility of the clamping block shaking or deviating during the movement, ensuring the accurate clamping of the ladder by the clamping block, and thus improving the reliability and stability of the entire ladder fixing device.

[0011] Preferably, the ladder includes a horizontal bar and vertical bars disposed at both ends of the horizontal bar. Multiple horizontal bars are disposed at intervals. Both ends of any horizontal bar are fixedly connected to the vertical bars. Each clamping block has a clamping groove for interlocking with the vertical bars.

[0012] By adopting the above technical solution, the clamping groove on the clamping block and the vertical rod are used to form an embedded fit, which increases the contact area between the ladder and the clamping block, so that the clamping block can firmly hold the vertical rod, thereby achieving stable fixation of the ladder, and also facilitating the installation and disassembly of the ladder by the staff.

[0013] Preferably, the support mechanism includes a fixed plate, a rotating rod, a sliding rod slidably mounted on the wall, a locking plate for engaging with a crossbar, and a return spring for resetting the rotating rod. The fixed plate is vertically mounted on the connecting base plate. One end of the rotating rod is rotatably connected to the fixed plate, and the other end is rotatably connected to the sliding rod. The end of the sliding rod away from the rotating rod forms a through-sliding engagement with the connecting base plate. The locking plate is mounted on the rotating rod. One end of the return spring is connected to the rotating rod, and the other end of the return spring is connected to the connecting base plate.

[0014] By adopting the above technical solution, when a ladder needs to be installed, the staff first manually operates the rotating rod to rotate it towards the wall, thereby causing the rotating rod to slide towards the wall. At this time, the return spring is in a compressed state. Then, the staff can operate the ladder to raise and lower it and adjust it to a suitable height. Then, the rotating rod is released. At this moment, the rotating rod returns to its initial state under the action of the return spring, and the locking plate on the rotating rod engages with the crossbar, thereby effectively enhancing the stability of the ladder.

[0015] Preferably, the connecting base plate is provided with a reinforcing frame for auxiliary support of the ladder, and the reinforcing frame is provided with a guide groove for guiding the ladder to move up and down, and the vertical rod and the guide groove form a guide sliding fit.

[0016] By adopting the above technical solution, the guide groove on the reinforcing frame and the vertical rod form a guiding sliding cooperation, which can help support the climbing ladder and increase its stability. On the other hand, during the installation or dismantling of the climbing ladder, the guide groove can play a guiding role, making the lifting and lowering of the climbing ladder smoother and more accurate, facilitating the operation of the staff, and further improving the stability and reliability of the climbing ladder fixing device.

[0017] Preferably, the end of the sliding rod away from the rotating rod is provided with a blocking block to prevent the sliding rod from detaching from the connecting base plate, and the blocking block forms an abutting fit with the connecting base plate.

[0018] By adopting the above technical solution, the blocking block and the connecting plate form an abutting fit, thereby effectively preventing the sliding rod from detaching from the connecting plate and ensuring the normal sliding movement of the sliding rod on the connecting plate. This ensures that the support mechanism can continuously and stably provide support for the ladder, guaranteeing the safety and stability of the ladder.

[0019] Preferably, the wall is provided with a waist-shaped hole to allow the sliding rod to slide.

[0020] By adopting the above technical solution and utilizing the waist-shaped hole, sufficient space is provided for the sliding rod to slide, avoiding interference between the sliding rod and the connecting plate during the sliding process. This ensures that the sliding rod can smoothly slide through, enabling the support mechanism to work normally and effectively enhancing the stability of the ladder.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By utilizing the clamping mechanism and support mechanism on the connecting base plate, the support mechanism can enhance the stability of the ladder, and the clamping mechanism can further effectively clamp and fix the ladder, thereby improving the stability of the ladder during use, reducing safety hazards, ensuring construction safety, and also helping to improve construction efficiency. 2. When a ladder needs to be installed, the worker first manually operates the rotating rod to rotate it towards the wall, thereby causing the sliding rod to slide towards the wall. At this time, the return spring is in a compressed state. Then, the worker can operate the ladder to raise and lower it and adjust it to a suitable height. Then, the rotating rod is released. At this moment, the rotating rod returns to its initial state under the action of the return spring, and the locking plate on the rotating rod engages with the crossbar, thereby effectively enhancing the stability of the ladder. 3. The double-acting screw is driven by a drive motor to rotate. The clamping blocks at both ends of the double-acting screw can move towards or away from each other on the double-acting screw, thereby realizing the clamping or releasing operation of the ladder.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0025] This application discloses a pre-embedded ladder support fixing device.

[0026] Reference Figure 1 and Figure 2 An embedded ladder support fixing device includes a connecting base plate 1 embedded in the building wall and a detachable ladder 2. Two sets of abutment plates 3 are provided on the side of the wall away from the connecting base plate 1. Two connecting bolts 4 are passed through each set of abutment plates 3 in parallel. Each connecting bolt 4 passes through the abutment plate 3, the wall and the connecting base plate 1 in sequence. The connecting bolt 4 is threaded to the connecting base plate 1 and locked to the connecting base plate 1 by a nut.

[0027] Reference Figure 1 and Figure 2 By using the contact plate 3 to contact the wall surface, compared to a single connecting bolt 4 acting directly on the wall, the force-bearing surface between the plate 3 and the wall is increased, so that the tightening force applied by the connecting bolt 4 is more evenly distributed on the wall, reducing local stress concentration and preventing the wall from being damaged or cracked due to uneven force, thereby achieving a stable connection between the connecting plate 1 and the wall.

[0028] Reference Figure 1 and Figure 2 The ladder 2 includes a horizontal bar 21 and vertical bars 22 fixed at both ends of the horizontal bar 21. Multiple horizontal bars 21 are provided. In this embodiment, three horizontal bars 21 are provided at intervals. The two ends of any horizontal bar 21 are welded to the vertical bars 22 respectively.

[0029] Reference Figure 1 and Figure 2 The connecting base plate 1 is provided with a clamping mechanism 5 and a support mechanism 6. Multiple sets of clamping mechanism 5 and support mechanism 6 are provided. In this embodiment, only one set of clamping mechanism 5 and support mechanism 6 is provided.

[0030] Reference Figure 1 and Figure 3 The clamping mechanism 5 includes a connecting plate 51, a bidirectional lead screw 52, ​​a drive motor 53, and two symmetrically arranged clamping blocks 54. The connecting plate 51 is vertically welded to the bottom of the connecting plate 51. The bidirectional lead screw 52 is horizontally arranged. The drive motor 53 is mounted on the connecting plate 51 through a flange. The output shaft of the drive motor 53 is coaxially fixed with the bidirectional lead screw 52 through a coupling. The two ends of the bidirectional lead screw 52 are respectively machined with reverse threads. The inner sides of the two clamping blocks 54 are provided with threaded holes that are threadedly connected to the bidirectional lead screw 52.

[0031] Reference Figure 2 and Figure 3 Each clamping block 54 has a sliding block 541 welded to the side opposite to the vertical rod 22. A straight sliding groove 11 is machined on the connecting base plate 1, and each sliding block 541 is slidably disposed in the sliding groove 11. Each clamping block 54 has a clamping groove 542 corresponding to the outer wall shape of the vertical rod 22. The clamping groove 542 of each clamping block 54 and the corresponding vertical rod 22 form an embedded fit.

[0032] Reference Figure 2 and Figure 3 When the drive motor 53 starts, the drive motor 53 drives the bidirectional lead screw 52 to rotate, causing the two clamping blocks 54 to move synchronously towards or away from each other along the sliding groove 11, thereby realizing the clamping or releasing operation of the vertical rod 22. This structural design makes the clamping operation highly automated and can ensure the synchronous movement of the two clamping blocks 54, making the clamping of the vertical rod 22 more uniform and stable, and improving the stability of the ladder 2 during use.

[0033] Reference Figure 4 and Figure 5The support mechanism 6 includes a fixed plate 61, a rotating rod 62, a sliding rod 63, a locking plate 64, and a return spring 65. The fixed plate 61 is vertically welded to the top of the connecting base plate 1. Limiting plates 611 are welded on the fixed plate 61. Two limiting plates 611 are spaced apart. A rotating shaft 612 is provided between the two limiting plates 611. The rotating shaft 612 is welded and fixed to the end of the rotating rod 62, and both ends of the rotating shaft 612 are rotatably connected to the limiting plates 611, so that the rotating rod 62 can rotate relative to the fixed plate 61.

[0034] Reference Figure 4 and Figure 5 One end of the rotating rod 62 away from the rotating shaft 612 is rotatably connected to the sliding rod 63 via a pin. A waist-shaped hole is provided through the wall. The end of the sliding rod 63 away from the rotating rod 62 forms a sliding fit with the waist-shaped hole of the connecting base plate 1. A blocking block 631 with a circular cross-section is welded to the end of the sliding rod 63 away from the rotating rod 62. The blocking block 631 is located on the side of the wall away from the ladder 2, and the blocking block 631 forms an abutting fit with the connecting base plate 1 to prevent the sliding rod 63 from completely disengaging from the waist-shaped hole.

[0035] Reference Figure 4 and Figure 5 The clamping plate 64 is welded to the rotating rod 62. The clamping plate 64 has a V-shaped structure and is used to clamp the crossbar 21. The clamping plate 64 and the return spring 65 are arranged opposite to each other. One end of the return spring 65 is bonded to the rotating rod 62, and the other end of the return spring 65 is bonded to the connecting base plate 1. The return spring 65 provides additional support force for the rotating rod 62, thereby enhancing the support effect on the ladder 2.

[0036] Reference Figure 4 and Figure 5 When ladder 2 needs to be installed, the staff first manually operates the rotating rod 62 to rotate it toward the wall, thereby rotating the rotating rod 62 to drive the sliding rod 63 to slide toward the wall. At this time, the return spring 65 is in a compressed state. Then, the staff can operate ladder 2 to raise and lower it and adjust it to a suitable height. Then, the rotating rod 62 is released. At this moment, the rotating rod 62 returns to its initial state under the action of the return spring 65, and the locking plate 64 on the rotating rod 62 engages with the crossbar 21, thereby effectively enhancing the stability of ladder 2.

[0037] Reference Figure 2 Symmetrical reinforcing frames 12 are welded to both sides of the connecting base plate 1. The reinforcing frames 12 are positioned between the support mechanism 6 and the clamping processing. A vertical guide groove 121 is provided through the outer wall shape of the corresponding vertical rod 22 on any reinforcing frame 12. Any vertical rod 22 and the corresponding guide groove 121 form a guide sliding fit, making the lifting and lowering of the ladder 2 smoother and more accurate, facilitating the operation of the staff, and further improving the stability and reliability of the ladder 2 fixing device.

[0038] The implementation principle of this application embodiment is as follows: In actual operation, the worker pushes the rotating rod 62 to move the clamping plate 64 towards the wall. At this time, the return spring 65 is compressed, and the sliding rod 63 slides into the wall along the waist-shaped hole. Then, the worker places the climbing ladder 2 on the ground from top to bottom through the guide groove 121 of the reinforcing frame 12, so that the vertical rod 22 of the climbing ladder 2 forms a guide sliding fit with the guide groove 121. Then, the worker raises the climbing ladder 2 and releases the rotating rod 62. The return spring 65 drives the clamping plate 64 to clamp the uppermost horizontal rod 21, completing the support and fixation. The drive motor 53 is started to drive the clamping blocks 54 at both ends of the bidirectional screw 52 to slide inward and clamp the vertical rod 22, further fixing the climbing ladder 2.

[0039] When construction workers climb, the pressure on the horizontal bar 21 also acts on the locking plate 64. The locking plate 64 drives the rotating rod 62 to rotate around the pin shaft, thereby causing the sliding rod 63 to move outward. At this time, the return spring 65 is in a stretched state, and the locking plate 64 and the horizontal bar 21 are locked together, which improves the stability of the ladder 2.

[0040] When it is necessary to remove the ladder 2, the staff will raise the ladder 2 again to separate the clamping plate 64 from the crossbar 21 on the ladder 2. Pull the rotating rod 62 to move the clamping plate 64 toward the wall. At this time, the ladder 2 can be moved upward and removed. After the ladder 2 is removed, the return spring 65 pushes the rotating rod 62 to return to its original position, ready for the next support action.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
