Description

Technical Field

[0001] The utility model belongs to the technical field of electric power operation and maintenance hoisting, in particular to a road cable trench cover hoisting lifting platform. Background Art

[0002] Cable trench, as an underground passage for laying cables, must have a certain pressure-bearing capacity, so its size and weight are relatively large. In the operation and maintenance of the power system, such as firewall inspection, cable inspection and maintenance, cable trench cleaning, etc., the cable trench cover needs to be lifted and removed.

[0003] At present, the traditional operation method is to open the cable trench cover by prying manually, but this method requires a lot of manpower, and the cable trench covers that are squeezed tightly together are often difficult to open, especially in some narrow spaces. There is a risk of stepping on empty space during construction, which can easily cause serious accidents such as casualties and cable damage. In addition, since the cable trench covers are relatively heavy and there are many of them, there is a risk of crushing fingers and the crowbar rebounding and injuring people when multiple people work together. If the cable trench cover is hoisted with a mechanical hoist, the existing technology lacks a load-bearing, construction, and transfer platform for the mechanical hoist, which to a certain extent affects the efficiency and convenience of hoisting the cable trench cover. Utility Model Content

[0004] The utility model solves the shortcomings of the prior art and provides a road cable trench cover plate hoisting lifting platform which improves the cable trench cover plate hoisting efficiency and convenience.

[0005] To achieve the above-mentioned purpose, the utility model first proposes a road cable trench cover lifting lifting platform, including a base frame, a scissors frame, a lifting platform and a driving cylinder. A walking wheel is arranged at the bottom of the base frame. One side of the bottom of the scissors frame is hinged to the base frame, and the other side is slidably assembled with the base frame. One side of the top of the scissors frame is hinged to the lifting platform, and the other side is slidably assembled with the lifting platform. One end of the driving cylinder is hinged to the base frame, and the other end is hinged to the sliding side of the bottom of the scissors frame.

[0006] In this embodiment, an opening larger than the cable trench cover is provided on the base frame directly below the lifting platform to form a lifting area, and a lifting ring is fixed at the bottom of the lifting platform at a position corresponding to the lifting area.

[0007] In the present embodiment, a scissors frame is respectively arranged on the base frame and on both sides of the lifting area, and the scissors frame includes a first scissor arm and a second scissor arm. The middle parts of the first scissor arm and the second scissor arm are hinged, one end of the first scissor arm is hinged to the base frame, and a load-bearing wheel is installed on the other end. The first scissor arm is slidably connected to the bottom of the lifting platform through the load-bearing wheel, one end of the second scissor arm is hinged to the lifting platform, and a load-bearing wheel is also installed on the other side, and the second scissor arm is slidably connected to the base frame through the load-bearing wheel; a stabilizing bar is fixed between the second scissor arms of the two scissor frames, the stabilizing bar is perpendicular to the plane where the scissors frames are located, one end of the driving cylinder is hinged to the base frame, and the other end is hinged to the stabilizing bar.

[0008] In this embodiment, the driving cylinder is a foot-operated driving cylinder, and a pedal for driving the foot-operated driving cylinder is also mounted on the base frame.

[0009] In this embodiment, the driving cylinder is a hydraulic cylinder or a pneumatic cylinder.

[0010] In this embodiment, the footrest is arranged on a side of the base frame away from the lifting area.

[0011] In this embodiment, a track is provided on the side of the base frame and the lifting platform that contacts the load-bearing wheel and on the moving route of the load-bearing wheel, and the track is slidably assembled with the load-bearing wheel.

[0012] With the above structure, the utility model has the following advantages:

[0013] 1. This device can be lifted and folded by a scissor frame and can be moved by the running wheels at the bottom of the frame, which improves the efficiency and convenience of cable trench cover hoisting;

[0014] 2. This device utilizes the hoisting area on the base frame that is larger than the cable trench cover, and uses the walking wheels to move the device to the top of the cable trench cover so that the hoisting area corresponds to the position of the cable trench cover. Then the lifting device can be installed using the lifting ring, and then the lifting platform is lifted by the scissor lift mechanism. The cable trench cover is lifted by the lifting device through the lifting platform to separate the cable trench cover from the cable trench, thereby saving labor and improving the efficiency of lifting the cable trench cover.

[0015] 3. This device adopts a scissor lift mechanism and a foot-operated drive cylinder. The scissor lift mechanism has the characteristics of high stability, large load capacity and smooth lifting, which ensures the stability of the cable trench cover installation. When the scissor lift mechanism is not needed, it can be folded and stored to save storage space. The foot-operated drive cylinder can reduce or eliminate the need for the operator to use both hands during operation. Since it is more labor-saving to step on the foot, the user's fatigue is reduced. Moreover, the foot-operated drive cylinder does not require an additional power supply or electronic control system. It has high stability, low cost and simple maintenance, and is suitable for the humid and dusty environment where the cable trench cover is used.

[0016] In summary, the present application greatly improves the efficiency and convenience of cable trench cover hoisting. BRIEF DESCRIPTION OF THE DRAWINGS
