Description

Lifting tool for cable trench cover

technical field

The utility model relates to a tool used in the cable laying and maintenance process, in particular to a mobile trolley for cable trench cover plates.

Background technique

In the construction work of power companies, laying cables is a regular work, and cables are generally installed in cable trenches. The cable trench of the substation uses a large number of cement cover plates. When threading or laying cables during maintenance and construction, the cover plate of the cable trench needs to be lifted. After the construction is completed, the cover plate is covered on the cable trench. The upper plane of the cover plate is generally flush with the ground, that is to say, although the cover plate is covered on the cable trench, the cover plate is embedded under the ground, and generally a trapezoid is formed on the ground on both sides of the cable trench. Put the cover plate into the stepped groove on the cable trench. In this way, when the cover plate needs to be lifted, generally a crowbar is inserted into the gap between the cover plate and the ground (or the gap between the cover plate and the cover plate), the cover plate is pried up, and then the cover plate is manually moved away from the cable trench . When the cover plate is covered on the cable trench, two people also carry the cover plate and put the cover plate in the groove of the cable trench. This construction method has the following problems: (1) When using a crowbar to pry the cover plate, because the gap between the cover plates is small, it is easy to damage the cover plate or the ground; (2) Since the staff moves the trench cover by hand When lifting the cover, due to the different strength of each person, the timing of lifting and lowering is inconsistent, which can easily cause the cover to crush the hand and pose a threat to the personal safety of the staff. (3) When manually moving the cover plate, due to the large size and heavy weight of the cover plate, many people are required to move it, generally more than 4 people. When the moving cover plate is tightly squeezed with the surrounding cover plates, It is also necessary to lift the cover plate with a crowbar first, and then lift the cover plate, so that more personnel are needed, which is time-consuming and labor-intensive.

Chinese patent document CN 202454983 U discloses a cable trench cover mobile trolley, comprising a vehicle body, handlebars and wheels, the handlebars and wheels are fixedly connected to the vehicle body respectively, and the wheels are located in the middle of the vehicle body; steel pipes are welded at the front end of the vehicle body; The two ends of the steel pipe are respectively provided with a movable hook, and the movable hook is inserted into the steel pipe. This tool for moving the cover plate still requires the cooperation of multiple people (at least two people), and its movable hook cannot directly clamp the cover plate, and it is necessary to manually insert the movable hook into the bottom of the cover plate, which is very difficult, or is almost impossible to achieve.

Utility model content

The technical problem to be solved by the utility model is to provide a tool for moving the cable trench cover plate which can be operated by one person and has high safety.

In order to solve the problems of the technologies described above, the technical solution adopted by the utility model is:

Cable trench cover lifting tool, including the main body of the frame mainly composed of wheels, axles and poles with handles connected to the axles. The poles and axles are installed through two sections of uprights A pick ring is set under the front end of the pick rod, and a clip for clamping the cover plate is connected to the pick ring through two double-ring hinge rods; the clip is mainly composed of two splints, and the middle parts of the two splints are connected by pins. The shafts are hinged, the lower ends of the two splints are provided with opposite clamping plates, and the upper ends of the two splints are provided with pull rings hinged with double-ring hinge rods.

The utility model is further improved in that:

The connection position of the wheel and the pick bar is biased to one side of the pick ring.

The double-ring hinge rod is a straight rod with rings at both ends, and the rings at both ends of the double-ring hinge rod are respectively socketed with the pick ring and the pull ring.

The clamping plate is a straight plate corresponding to the width of the cover plate.

Owing to adopting above-mentioned technical scheme, the beneficial effect that the utility model produces is:

The utility model can clamp the cover plate by setting the clip at the front end of the pick bar, and then put the cover plate on the cable ditch or beside the cable ditch by rotating the pick bar. It can be operated by one person without the assistance of others, and the operator can complete the work of lifting and placing the cover without touching the cover.

When the clip of the present utility model is in the process of descending (raising the horizontal handle of the cantilever), if it touches the top of the cover plate, the double-ring hinge rod at the upper end of the clip will relax, the lower end of the clip will open, and the two clamping plates will slide to the Both sides of the cover plate (even if the cover plate is covered on the cable trench, there will be a gap between the cover plates, or between the cover plate and the ground. At this time, the clamping plate will automatically enter the gap by gravity and block the cover plate) , when the front end of the pick rod is lifted up, the double-ring hinge rod will be tensed, and the upper end of the clip will be pulled to shrink inwardly, and the clamp plate at the lower end of the clip will first clamp the cover plate, and when the front end of the pick rod continues to rise, the clamp will lock the cover plate The board is clamped up. Then by turning the pick bar to make the pick bar rotate around the column and the bearing, the cover plate can be moved away from the original position or covered on the cable trench.

The utility model uses the axle as the lever fulcrum of the pole. When the distance from the fulcrum to the horizontal plate is longer than the distance to the heavy object (cover plate), it is relatively labor-saving when lifting the cover plate, and after lifting, the cover plate can also be wound around the axle. The upper column rotates to lift the cover out of its original position. The clamp of the utility model relies on the principle of a lever and a connecting rod after the clamping plates clamp the cover plate, and the two clamping plates will exert force inward so that the cover plate will not fall off.

Detailed ways

Below in conjunction with accompanying drawing 1,2 the utility model is described in further detail:

The cable trench cover lifting tool comprises two wheels 1 connected by the axle 2, and a pick bar 6 is connected above the axle 2, and the pick bar 6 can be an iron pipe. The connection of pick bar 6 and axle shaft 2 is to connect by two sections of columns 3 and the bearing 4 that is installed between two sections of columns 3, and bearing 4 is installed between two sections of columns, so that pick bar 6 can column be fulcrum rotation. The vehicle frame main body that wheel 1, axle shaft 2, pick bar 6, column 3, bearing 4 constitute can push forward. The connection position of wheel 1 and pick bar 6 should deviate to the front end of pick bar, promptly away from the position of following handlebar, and deflect to the side where following pick ring 7 is at.
