Description

Technical Field

[0001] This utility model relates to the field of arch frame trolley technology, specifically an arch frame operation basket. Background Technology

[0002] The arch frame trolley is a specialized piece of equipment used in tunnel and underground engineering construction. It uses a hydraulic arm as a robotic arm and a suspended basket to provide a stable high-altitude working platform for construction workers. It lifts and positions heavy arch frame segments at the tunnel face and assists in high-risk high-altitude operations such as arch frame installation, welding, anchor bolt construction, and quality inspection. This enables automated / semi-automated handling, positioning, adjustment, and temporary fixing of key load-bearing structures in the initial support of tunnels, such as steel arch frames and grid arch frames, significantly improving the safety, efficiency, and quality of construction.

[0003] Existing arch frame trolley-type work platforms transport construction workers to target work locations (such as bolt holes, welding connecting plates, and installing anchor bolts). However, since these work platforms are mostly fixed structures and these work locations are distributed at different positions on the arch frame, it is difficult for construction workers to be in the most suitable working position during some operations due to the limited space on the platform. This forces workers to lean out of the platform or frequently move the arch frame trolley to complete the work, which not only increases the safety risks of working at heights but also leads to poor work efficiency. Therefore, an arch frame work platform is now provided to eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0039] In one embodiment, such as Figures 1-5 As shown, an arch frame work basket includes a base 1, a boom 5 is installed at the bottom of the base 1, two guard rods 4 are symmetrically arranged above the base 1, and two support columns 3 are symmetrically fixedly connected to the outer walls of the two guard rods 4. The two support columns 3 are fixedly connected to the base 1, and an extension mechanism for extending the range of motion is provided on the base 1.

[0040] The extension mechanism includes two limiting slide plates 203 symmetrically slidably connected inside the base 1. The two limiting slide plates 203 extend to the outside of both ends of the base 1. An extension frame 201 is fixedly connected to the ends of the two limiting slide plates 203 that are far apart from each other. The extension frame 201 is C-shaped and is slidably connected to the base 1. The support column 3 is located inside the extension frame 201. A door panel 208 is rotatably connected to the inside of the extension frame 201.

[0041] In this embodiment, when in use, the construction personnel move between the two protective bars 4. At this time, the door panel 208 can be easily locked and fixed by the expansion mechanism, thereby effectively preventing the door panel 208 from opening by itself when the construction personnel are working.

[0042] Then, the boom 5 can be used to move the construction personnel and the arch frame to the designated location for construction work. During this process, when the movable space on the base 1 is insufficient, the movable space can be easily expanded through the expansion mechanism, thereby effectively reducing the safety risks of high-altitude operations. When it is necessary to reduce the movable space, the above operation is reversed, which can bring the two limit slides 203 closer to each other, so as to further improve the efficiency of construction work.

[0043] In one embodiment, such as Figures 2-5 As shown, the extension mechanism also includes a rotating assembly mounted on the base 1;

[0044] The rotating assembly includes: a transmission rod 207 rotatably connected inside the base 1, the transmission rod 207 being located below the two limiting slide plates 203, and two movable sleeves 206 symmetrically slidingly sleeved on the outer wall of the transmission rod 207, the two movable sleeves 206 being fixedly connected to the two limiting slide plates 203 respectively, and both movable sleeves 206 being slidably connected to the base 1.

[0045] The base 1 is equipped with a drive assembly for driving the transmission rod 207 to reciprocate.

[0046] The movable sleeve 206 is provided with a guide component for driving the movable sleeve 206 to move;

[0047] The extension frame 201 is provided with a first limiting component for sliding limit of the extension frame 201;

[0048] The expansion frame 201 is provided with a locking component for locking and fixing the door panel 208;

[0049] The drive assembly includes: a hydraulic push rod 204 installed inside the base 1, a heat dissipation groove for the hydraulic push rod 204 to dissipate heat at the junction of the base 1 and the hydraulic push rod 204, a gear ring 202 fixedly connected to the outer wall of the transmission rod 207, a rack 205 meshing with the outer wall of the gear ring 202, the rack 205 being located below the transmission rod 207, the rack 205 being fixedly connected to the output end of the hydraulic push rod 204, and the rack 205 being slidably connected to the base 1;

[0050] The guide assembly includes: multiple guide sliders 2010 that are circumferentially and equidistantly fixed inside the movable sleeve 206. The outer walls of the multiple guide sliders 2010 are all hemispherical. A guide groove is provided at the junction of the transmission rod 207 and the guide slider 2010 for the guide slider 2010 to slide. Through the cooperation of the rotating assembly, the driving assembly and the guide assembly, the two limiting slide plates 203 can be controlled to move closer or further apart, so as to make convenient adjustments to the movable space.

[0051] In one embodiment, such as Figures 1-2 As shown, the first limiting component includes:

[0052] Two limiting sleeves 209 are symmetrically fixedly connected to the inner wall of the expansion frame 201. The two limiting sleeves 209 are slidably sleeved on the outer walls of the two protective rods 4. Through the mutual cooperation of the two limiting sleeves 209 and the two protective rods 4, the expansion frame 201 can be moved and limited.

[0053] In one embodiment, such as Figures 1-4As shown, the engaging assembly includes a positioning block 2014 that is slidably connected inside the extension frame 201. The bottom outer wall of the positioning block 2014 is inclined, and the positioning block 2014 penetrates through the extension frame 201 to the interior of the door panel 208.

[0054] The positioning block 2014 is equipped with a second limiting component;

[0055] The second limiting component includes: a connecting slide rod 2012 fixedly connected to the top of the positioning insert 2014, the connecting slide rod 2012 extending through to the outside of the top of the expansion frame 201, the connecting slide rod 2012 being slidably connected to the expansion frame 201, and a connecting stop 2011 fixedly connected to the top of the connecting slide rod 2012, the connecting stop 2011 being in contact with the upper surface of the expansion frame 201;

[0056] A reset component is provided on the connecting slide bar 2012;

[0057] The reset assembly includes a spring 2013 sleeved on the outer wall of the connecting slide bar 2012. One end of the spring 2013 contacts the inner wall of the expansion frame 201, and the other end of the spring 2013 contacts the outer wall of the positioning insert 2014. Through the cooperation of the locking assembly, the second limiting assembly and the reset assembly, the door panel 208 can be easily locked and fixed.

[0058] The above embodiment discloses an arch frame operation basket. In use, when the construction personnel move between the two guardrails 4, the rotating door panel 208 contacts one side of the inner wall of the expansion frame 201. At the same time, under the pressure of the outer wall of the door panel 208, the positioning block 2014 pushes the connecting stop 2011 and the upper surface of the expansion frame 201 through the connecting slide rod 2012 to separate from each other. At this time, the positioning block 2014 retracts by moving the compression spring 2013. When the door panel 208 is in complete contact with the inner wall of the expansion frame 201, the spring 2013 pushes the positioning block 2014 into the interior of the door panel 208 by rebounding. This allows the door panel 208 to be easily locked and fixed, thereby effectively preventing the door panel 208 from rotating open on its own when the construction personnel are working.

[0059] Afterwards, the boom 5 can be used to move the construction personnel and the arch frame to the designated location for construction work. During this process, when the movable space on the base 1 is insufficient, the hydraulic push rod 204 is activated to push the rack 205 to move. At the same time, the gear ring 202, driven by the meshing of the rack 205, drives the transmission rod 207 to rotate. At this time, the transmission rod 207 squeezes the outer wall of the guide slider 2010 through the guide groove, so that the guide slider 2010 can slide along the inner wall of the guide groove under the squeezing and guidance of the inner wall of the guide groove. At the same time, the moving sleeve 206, driven by the guide slider 2010, drives the limiting slide plate 203 to slide along the inner wall of the base 1. At this time, the expansion frame 201, driven by the limiting slide plate 203, drives the limiting sleeve 209 to slide along the outer wall of the guard rod 4. This allows for convenient expansion of the movable space, thereby effectively reducing the safety risks of high-altitude operations.

[0060] When it is necessary to reduce the available space, the above operation is reversed, which brings the two limiting slides 203 closer together, thereby further improving the efficiency of the construction operation.

[0061] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
