Abstract
Description
Technical Field
[0001] The utility model relates to the field of tunnel construction frames, in particular to a novel telescopic construction platform frame used for tunnel construction. Background Art
[0002] During the tunnel excavation process, a construction platform is needed to provide a stable working platform for the drilling equipment. During the first phase of tunnel construction, hard rocks will be blasted. For example, in the drilling and blasting method, the accuracy and angle of the drilling are crucial to the subsequent blasting effect. The construction platform can lift the drilling equipment to the appropriate height and position to ensure the smooth progress of the drilling operation. After removing the slag from the blasted rocks, construction workers often use the construction platform to install the steel arch frame used for tunnel construction at the arch crown and arch waist. At this time, the role of the construction platform is to send construction workers to the vicinity of the arch crown and arch waist for easy installation.
[0003] Disadvantages of ordinary construction scaffolds:
[0004] 1. During the construction process, the construction platform needs to be moved to the section for construction, and when blasting, the platform needs to be moved to a place far away from the blasting site. However, such a construction platform cannot be moved by manpower alone, and a forklift or large excavator is required to drag the platform to the construction site. Therefore, an excavator or forklift is often required for auxiliary movement during construction, which not only occupies construction resources but also affects the construction progress;
[0005] 2. Due to construction needs, construction workers need to use a construction platform to install the steel arch frame at the arch waist. However, because the steel arch frame is long and very heavy, it is impossible to install the steel arch frame at the arch waist by just standing on the work platform. A ladder is often needed for auxiliary construction. This method is inefficient and very dangerous.
[0006] 3. The length of the first platform of the construction platform is fixed. Therefore, during construction, the construction workers often cannot reach the wall at the waist of the arch because the platform is too far away from the wall. If the first platform is too long, the entire construction platform will be too long, making it inconvenient to move horizontally in the tunnel section;
[0007] 4. When workers are working on the upper platform, due to the use of electric welding and other equipment, sparks, dust and rocks often splash to the bottom of the platform, causing the construction workers at the bottom of the platform to be unable to work at the same time as the upper workers, delaying the construction process;
[0008] 5. There are many wires on the construction platform, and they are often tangled and placed randomly during construction, which poses a safety hazard;
[0009] 6. Since the steel arch is transported to the upper table surface by an excavator or a forklift during construction and then moved from the upper table surface to the arch waist or arch top for installation, in order to facilitate transportation, guardrails are usually not installed on the construction bench, posing a safety hazard.
[0010] Therefore, the present utility model provides a novel telescopic construction bench for tunnel construction. Summary of the Utility Model

A first support rod is bolted between the first table surface and the support columns, and a second support rod is bolted between the upper table surface and the support columns. The bottom of the support column is fixedly connected with a telescopic wheel assembly. The telescopic wheel assembly includes a storage seat, a hydraulic cylinder, and a moving wheel. A sliding plate is slidably connected to the inner cavity of the storage seat. The upper side of the storage seat is bolted with a hydraulic cylinder, and the lower side of the telescopic end of the hydraulic cylinder is connected to the sliding plate. A moving wheel is installed on the lower side of the sliding plate. An extension plate is slidably connected to the first table surface, and a telescopic guardrail is installed on the upper table surface.
[0013] Preferably, a limiting block is provided at the bottom of the inner cavity of the storage seat.
[0014] Preferably, a protection plate is bolted between the second support rods.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:
[0019] 1) With the construction bench of the present utility model, when the construction bench needs to be moved, by extending the moving wheels to contact the ground and reaching an appropriate support height, it can be conveniently moved;
[0020] 2) By providing an extension plate on the first table surface, the length at both ends can be lengthened, facilitating construction;
[0021] 3) Through the setting of the protective plate, it can prevent dust from falling and the sputtering of sparks. An electric wire storage box is installed on the protective plate, which is convenient for storing electric wires;
[0022] 4) Through the setting of the retractable guardrail, when no construction work is carried out, the retractable guardrail is retracted into the storage board, and when construction is carried out, the retractable guardrail is extended, which can play a very good protective role for the staff;
[0023] 5) A goods transportation platform is placed directly below the upper table surface. By installing pulleys or other components on the upper table surface to pull the goods, the purpose of transporting the steel arch frame from the bottom of the bench to the upper table surface can be achieved, avoiding the use of excavators and forklifts to transport goods.

Steel ladders are also installed on the upper tabletop 18 and the first tabletop 5. The bottom of the support column 1 is fixedly connected to a telescopic wheel assembly 2. The telescopic wheel assembly 2 includes a storage seat 13, a hydraulic cylinder 15 and a moving wheel 16. A sliding plate 14 is slidably connected to the inner cavity of the storage seat 13. The hydraulic cylinder 15 is bolted to the upper side of the storage seat 13. The lower side of the telescopic end of the hydraulic cylinder 15 is connected to the sliding plate 14. The moving wheel 16 is installed on the lower side of the sliding plate 14. The position of the moving wheel 16 is adjusted by the hydraulic cylinder 15.
