Technical Field

The utility model relates to a bridge construction hoist field, especially an easy bridge construction hoisting accessory who rotates.

Background

At present, when construction is carried out, tools or materials on the ground are often lifted to the bridge deck by various lifting appliances. One of the more used lifting appliances is a derrick crane, also called a triangular crane; the device consists of a bracket, a winch, a movable pulley and other components; the crane is convenient to build and has a small volume; the hoisting device can be directly placed above a bridge floor or a building, so that the rapid hoisting is realized; however, the crane has a simple structure, most derrick cranes cannot rotate, namely, the hoisted goods cannot be rotated to the bridge floor; people are required to pull the goods, so that certain danger is caused; meanwhile, some derrick cranes can rotate, but when the goods are heavy, the friction force on the rotating part is too large, the rotating resistance is large, and the rotating part is easily subjected to excessive abrasion. Therefore, the problem that the derrick mast crane is inconvenient to rotate needs to be solved at present.

Disclosure of Invention

To the situation, for solving the problem that exists among the prior art, the utility model aims at providing an easy pivoted bridge construction hoisting accessory, can effectively solve the gin pole and hang the inconvenient problem of rotation.

The technical scheme for solving the problem is that the derrick crane comprises a base, a vertical rod, a tripod, a winch, a movable pulley and a lifting hook, wherein the tripod is rotatably connected with the vertical rod; the right end of the base is provided with a plurality of detachable vertical connecting rods, the upper ends of the two connecting rods are provided with a horizontally placed arc-shaped plate, and an inverted T-shaped sliding groove is formed in the arc-shaped plate; a vertical pull rod is fixed at the right end of the tripod, and a slide block arranged in the chute is arranged at the lower end of the pull rod; the tripod rotates, enables the slider and rotates along the spout.

The utility model greatly reduces the resistance of the derrick mast during rotation and avoids excessive wear; the service life of the whole device is prolonged, the manpower is reduced, and the operation is convenient.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model comprises a derrick crane consisting of a base 1, a vertical rod 2, a tripod 3, a winch 4, a movable pulley 5 and a hook 6, wherein the tripod 3 is rotatably connected with the vertical rod 2; the right end of the base 1 is provided with a plurality of detachable vertical connecting rods 7, the upper ends of the two connecting rods 7 are provided with a horizontally placed arc-shaped plate 8, and an inverted T-shaped sliding groove 9 is formed in the arc-shaped plate 8; a vertical pull rod 10 is fixed at the right end of the tripod 3, and a slide block 11 arranged in the chute 9 is arranged at the lower end of the pull rod 10; the rotation of the tripod 3 enables the rotation of the slider 11 along the runner 9.

In order to realize the rotary connection between the tripod 3 and the vertical rod 2, the upper end of the vertical rod 2 and the middle part of the tripod are installed through a bearing.

In order to realize the disassembly of the connecting rod 7, the lower end of the connecting rod 7 is fixedly connected with the base 1 through a bolt 12.

In order to reduce the friction force when the sliding block 11 slides in the sliding chute 9, a roller 13 arranged in the sliding chute 9 is arranged on the sliding block 11; the rollers 13 are two left and right.

In order to adapt to the rotation angle of the tripod 3, the arc angle of the arc plate 8 is 90-180 degrees.

When the utility model is used, the whole device is firstly fixed on the bridge floor, and a heavy object is pressed on the base 1, so that the whole base 1 is kept stable; the tripod 3 in the device is formed by welding a plurality of support rods, and plays a role in supporting goods and turning; through the rotation of tripod 3, can make the goods rotate along with it, fall the place that needs the whereabouts, need not artificially go to hook and draw the goods.

In the device, a vertical pull rod 10 is connected to the right end of the tripod 3, the lower end of the pull rod 10 is arranged in a sliding groove 9 of an arc-shaped plate 8 through a sliding block 11, and the arc-shaped plate 8 is connected with a base 1 through a plurality of front and rear connecting rods 7; the curved plate 8 will remain stable; then, the right end of the tripod 3 is tensioned by the base 1 through the matching of the sliding block 11 and the sliding groove 9; meanwhile, the rotation of the tripod 3 is realized through the matching of the sliding block 11 and the sliding groove 9.

In the traditional derrick cranes, when lifting goods, the force of the goods is applied to the left end of the tripod 3; therefore, the whole tripod 3 takes the connecting part of the tripod 3 and the vertical rod 2 as a supporting point, and the rotating parts of the tripod and the vertical rod 2 can bear larger shearing force; thereby affecting the rotation of the tripod 3 and increasing the wear.

In the device, after the right end of the tripod 3 is connected through the connecting rod 7, the arc-shaped plate 8, the pull rod 10 and the slide block 11, the base 1 can pull the right end of the tripod 3 at the moment, so that the left end and the right end of the tripod 3 are kept in stress balance, and the stress condition of the connecting part between the tripod 3 and the vertical rod 2 is reduced; meanwhile, due to the matching of the sliding block 11 and the sliding groove 9; when the goods rise to the bridge floor after, when needing to place on the bridge floor, also can be light rotate tripod 3, make whole goods rotate along with it, realize the whereabouts.

The connecting rod 7 and the base 1 in the device can be detachably connected, so the arc-shaped plate 8 can be removed; the disassembly of the whole device is convenient, and the arc-shaped plate 8 also can not be installed when heavy goods do not need to be hoisted. Only when hoisting heavy goods, the hoisting device can save labor and protect the connecting piece.

The device is skillfully provided with a pull rod 10, a slide block 11, an arc-shaped plate 8 and a connecting rod 7 between the right end of the tripod 3 and the base 1; the right end of the tripod 3 is pulled by the base 1; therefore, when goods are hoisted, the left end and the right end of the tripod 3 are stressed in balance, the tripod 3 is prevented from inclining, and the abrasion of a connecting piece between the tripod 3 and the vertical rod 2 is reduced; the resistance in rotation is favorably reduced, and the rotation of the tripod 3 is facilitated.

The utility model has the advantages of convenient operation, ingenious structure, low cost, convenient manufacture, safety and effectiveness, greatly reduces the resistance of the derrick mast crane during rotation, and avoids excessive abrasion; the service life of the whole device is prolonged, the manpower is reduced, and the operation is convenient.
