Technical Field
[0001] This utility model relates to the field of ladder technology, and in particular to a reinforcement device for a sewage inspection well ladder. Background Technology
[0002] Wastewater inspection wells are auxiliary structures in drainage pipeline systems used for inspection, dredging, and maintenance. They primarily serve the wastewater pipeline network, ensuring its normal operation and preventing blockages. They are usually located at pipe intersections, bends, or slope changes to facilitate manual or mechanical access for dredging and maintenance.
[0003] Existing inspection wells have multiple ladders installed on their inner walls for personnel to go up and down. However, these ladders are made of multiple U-shaped steel bars, which can easily deform over long-term use, affecting their safety. To address this issue, we propose a reinforcement device for sewage inspection well ladders. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that the inner wall of the existing inspection well is equipped with multiple ladders for personnel to go up and down. However, the ladders are made of multiple U-shaped steel bars, which makes them prone to deformation after long-term use, thus affecting the safety of the ladders. Therefore, a reinforcement device for the ladders of sewage inspection wells is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A reinforcement device for a sewage inspection well ladder includes a ladder body, an installation mechanism mounted on the surface of the ladder body, and a connecting mechanism fixedly connected to the outer side of the installation mechanism. The connecting mechanism includes a connecting block, a fixing plate fixedly connected to the outer end of the connecting block, and a fixing stud fixedly connected to the surface of the fixing plate. A reinforcement plate is mounted on the surface of the fixing stud by a limiting nut. A support mechanism is fixedly connected to the inner side of the installation mechanism, and an anti-slip mechanism is installed inside the support mechanism.
[0006] Preferably, the installation mechanism includes a first retaining sleeve, and both ends of the ladder body are fitted with a first retaining sleeve and a second retaining sleeve, with a first mounting bolt installed between the first retaining sleeve and the second retaining sleeve.
[0007] Preferably, two fixing studs are symmetrically installed on the surface of the fixing plate.
[0008] Preferably, the support mechanism includes a transverse strut, the surface of the second sleeve is fixedly connected to the transverse strut, and the outer side of the transverse strut is threaded with a second mounting bolt.
[0009] Preferably, the anti-slip mechanism includes a plug-in block, the plug-in block is inserted inside the transverse support rod, and a foot pedal is fixedly connected to the upper end of the plug-in block.
[0010] Preferably, the surface of the foot pedal is fixed with multiple anti-slip rubber strips, and the surface of each anti-slip rubber strip is provided with anti-slip texture.
[0011] Preferably, there are two second mounting bolts, and the plug block has a slot that matches the second mounting bolt.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The device can be installed by the first and second clamps, which can facilitate the installation of the fixing plate and the horizontal support rod. The reinforcing plate can be installed on the surface of the fixing stud by the limiting nut, which can facilitate auxiliary support between multiple sets of climbing ladder bodies. At the same time, the horizontal support rod can provide lateral support for the climbing ladder body to prevent deformation, thus effectively reinforcing multiple climbing ladder bodies.
[0013] 2. This device allows the second mounting bolt to pass through the horizontal support rod and be inserted into the plug-in block by inserting the plug-in block into the horizontal support rod. This facilitates the installation of the foot pedal and the multiple anti-slip rubber strips on the surface of the foot pedal increase the friction when people step on the ladder body by contacting the anti-slip rubber strips.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] Reference Figure 1-4 A reinforcement device for a sewage inspection well ladder includes a ladder body 1. An installation mechanism 2 is installed on the surface of the ladder body 1, and a connecting mechanism 3 is fixedly connected to the outside of the installation mechanism 2. The connecting mechanism 3 includes a connecting block 31. A fixing plate 32 is fixedly connected to the outer end of the connecting block 31, and a fixing stud 33 is fixedly connected to the surface of the fixing plate 32. A reinforcement plate 4 is installed on the surface of the fixing stud 33 by means of a limiting nut 34. The limiting nut 34 is threaded onto the surface of the fixing stud 33, which can facilitate the limiting installation of the reinforcement plate 4. A support mechanism 5 is fixedly connected to the inside of the installation mechanism 2, and an anti-slip mechanism 6 is installed inside the support mechanism 5.
[0018] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the installation mechanism 2 includes a first clamping sleeve 21. The first clamping sleeve 21 and the second clamping sleeve 22 are engaged on both ends of the ladder body 1. A first mounting bolt 23 is installed between the first clamping sleeve 21 and the second clamping sleeve 22. The first mounting bolt 23 passes through the first clamping sleeve 21 and the second clamping sleeve 22, which facilitates the installation and connection between the first clamping sleeve 21 and the second clamping sleeve 22.
[0019] Furthermore, refer to Figure 2 and Figure 3 It can be seen that there are two fixing studs 33 symmetrically installed on the surface of the fixing plate 32. By symmetrically installing two fixing studs 33, the reinforcing plate 4 can be conveniently connected and supported between multiple ladder bodies 1.
[0020] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the support mechanism 5 includes a horizontal support rod 51, the surface of the second sleeve 22 is fixedly connected to the horizontal support rod 51, and the outer side of the horizontal support rod 51 is threaded with a second mounting bolt 52. The horizontal support rod 51 can provide horizontal support and reinforcement for the ladder body 1.
[0021] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the anti-slip mechanism 6 includes a plug block 61. The plug block 61 is inserted inside the transverse support rod 51, and the upper end of the plug block 61 is fixedly connected to a foot pedal 62. Through the plug block 61 and the foot pedal 62, the surface friction of the ladder body 1 can be easily increased when in use.
[0022] Furthermore, refer to Figure 2 and Figure 4 It can be seen that multiple anti-slip rubber strips 63 are fixed on the surface of the pedal 62, and anti-slip textures are opened on the surface of the multiple anti-slip rubber strips 63. The friction of stepping can be increased by the multiple anti-slip rubber strips 63 and the anti-slip textures opened on their surfaces.
[0023] Furthermore, refer to Figure 2 and Figure 4 It can be seen that there are two second mounting bolts 52, and the plug block 61 has a slot that matches the second mounting bolts 52. By having two second mounting bolts 52, the installation stability of the plug block 61 can be increased.
[0024] Working principle: When the ladder body 1 is in use, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 By engaging the first ferrule 21 and the second ferrule 22 onto the surface of the ladder body 1, and connecting the first ferrule 21 and the second ferrule 22 with the first mounting bolt 23, the reinforcing plate 4 is then fitted onto the surface of the fixing stud 33, and the limiting nut 34 is threaded onto the surface of the fixing stud 33, which can limit the reinforcing plate 4. At the same time, the plug block 61 is inserted into the transverse support rod 51, so that the second mounting bolt 52 can pass through the transverse support rod 51 and be inserted into the plug block 61, limiting the installation of the plug block 61. Thus, the reinforcing plate 4 and the transverse support rod 51 can easily reinforce the multiple ladder bodies 1. At the same time, the step pedal 62 and multiple anti-slip rubber strips 63 can increase the anti-slip effect when the user steps on the ladder body 1. The above is the complete working principle of this utility model.
