Description

Technical Field

[0001] The utility model relates to a construction tool, in particular to a mobile cart used for high-altitude installation operations in long and large tunnels. Background Art

[0002] At present, in the process of infrastructure construction, more and more tunnels appear, and many working conditions require high-altitude operations, such as subways, railways and highway tunnels in rail transit. Generally, electric lifts are used to transport the electric lifts to the work site, and then the required materials and operators are put on the work platform of the electric lifts, and then the machine is started. After the machine is raised to a certain height, the work is completed and then the site can be withdrawn. However, in actual construction, the site is often not friendly, such as lack of power access, the site does not allow the electric lift to enter (such as the ground has not been cleared), etc., and the electric lift is not adaptable and the cost is also high, which has a great impact on the construction progress. Summary of the invention

[0003] In order to cope with the above-mentioned special scenarios, the utility model provides a mobile cart for high-altitude installation operations in long and large tunnels, including walking wheels, a base, and a cart frame body. The base is a rectangular three-dimensional frame, and the walking wheels are installed under the four bottom corners of the base. The cart frame body is integrated with the base and is slightly narrower than the base. A plurality of diagonal braces are arranged on the base and the cart frame body, a working platform with a guardrail is arranged on the upper part of the cart frame body, and climbing ladders are provided on the sides of the base and the cart frame body.

[0004] Furthermore, in order to adapt to uneven and unclean construction sites, the front and rear sets of running wheels are configured with the front running wheels being small and the rear running wheels being large, and a brake device is provided on the rear running wheels.

[0005] Furthermore, in many cases, especially when power supply is inconvenient, in order to protect the workers more safely when climbing, a cylindrical protective cover is provided on the outside of the climbing ladder, and the cylindrical protective cover is one of a closed type or a mesh type.

[0006] Furthermore, in order to prevent other machines from colliding with the mobile cart during operation, reflective warning signs are provided on the outside of the base and the cart frame body.

[0007] Furthermore, in order to protect the safety of the workers, the working platform is a working space formed by installing a transverse protection rod after the cart frame body is extended upward. The bottom of the working platform is surrounded by four transverse rods fixed to the cart frame body to form a rectangular frame. A bottom surface is set in the rectangular frame, and a guardrail is formed by extending the cart frame body upward and surrounded by transverse protection rods.

[0008] The utility model has the advantages of low cost, strong adaptability, no need for electric drive, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Note: This figure is only for illustration of the results, and does not limit the size ratio. DETAILED DESCRIPTION

[0011] The utility model is described in detail below in conjunction with the accompanying drawings.

[0012] A mobile cart for high-altitude installation operations in long and large tunnels includes walking wheels 1, a base 2, and a cart frame body 3. The base 2 is a rectangular three-dimensional frame. The walking wheels 1 are installed under the four bottom corners of the base 2. The cart frame body 3 is integrated with the base 2 and is slightly narrower than the base. A plurality of diagonal braces 4 are arranged on the base 2 and the cart frame body 3. A working platform 5 with a guardrail is arranged on the upper part of the cart frame body 3. Climbing ladders 6 are arranged on the sides of the base 2 and the cart frame body 3.

[0013] The front and rear two sets of running wheels are arranged such that the front running wheels are small and the rear running wheels are large, and a brake device 7 is arranged on the rear running wheels. A cylindrical protective cover 8 is arranged on the outside of the climbing ladder 6, and the cylindrical protective cover is one of a closed type or a mesh type. Reflective warning signs 9 are arranged on the outside of the base 2 and the trolley frame body 3. The working platform 5 is a working space formed by installing a transverse protection rod after the trolley frame body 3 is extended upward. The bottom of the working platform is surrounded by four transverse rods fixed to the trolley frame body to form a rectangular frame, and a bottom surface 10 is arranged in the rectangular frame. The guardrail is surrounded by the transverse guard rod extending upward from the trolley frame body.

[0014] When work is needed, it is only necessary to push the mobile cart for high-altitude installation work in long tunnels to the designated position. The operator climbs up the work platform along the climbing ladder 6. Because of the setting of the fence, the operator can work safely on the work platform without worrying about falling and getting injured due to unstable gravity. When entering the site, sometimes the entrance height is not enough because the construction at the entrance is not complete or the site is not completely removed. Just tilt it backwards to lower its operating height and enter the site smoothly. When the site is not completely removed or uneven, it is also tilted, and the rear walking wheels are used as support to move forward, because the radius of the rear walking wheels is large, it can easily cross uneven bottom surfaces and obstacles. During the construction process, if a machine enters the site, even if the lighting is not enough and the machine operator cannot see the operation, as long as the machine's lighting lamp shines on the reflective warning sign from a distance, the machine can be reminded to bypass the operating range to avoid accidents.

[0015] Through the adaptive design of the utility model, during the on-site construction process, the work can be completed at a low cost, effectively avoiding construction obstacles due to inconvenient electricity and site restrictions.
