Abstract
The utility model discloses a lifting appliance for a concrete pole lift truck. The lifting appliance solves the problems that when a concrete pole is loaded and unloaded with an existing steel wire rope, time and labor are wasted, and operation is unsafe. The lifting appliance comprises a left-right symmetrical clamp body, the clamp body is in a dovetail connection type, pliers arms are arranged at the upper portion of the clamp body, pliers teeth are arranged at the lower portion of the clamp body, the two pliers teeth are closed to form a pliers opening radian to correspond to the radian of an outer wall of the concrete pole, the arc length of the pliers opening is larger than three fourth of the perimeter of the concrete pole, and lifting rings are in shaft connection with the top ends of the two pliers arms. The lifting appliance for the concrete pole lift truck saves the process of threading and binding the steel wire rope, improves loading efficiency, and reduces labor strength, transferring cost of the concrete pole and safety risks of stuff.
Description
Technical field
The utility model relates to a kind of lifting device.
Background technology
In the electric power erection process, need a large amount of concrete electric pole of transportation.On-the-spot concrete electric pole is all in heaps to be piled up depositing, and in the entrucking process, needs earlier with sling one of concrete electric pole of crane; Could be steel rope through concrete electric pole bottom; Length consuming time influences loading speed, unloads in the steel rope process wearing simultaneously; Operating personal is in one's hands by wire rope grip easily, has certain potential safety hazard.
Summary of the invention
In order to improve concrete electric pole loading-unloading vehicle speed, the utility model provides a kind of New Concrete electric pole loading-unloading vehicle to use suspender, and this suspender can substitute in traditional hanging method the steel rope of binding concrete electric pole, thereby reaches quick, the safe purpose that the concrete electric pole is lifted.
For realizing the foregoing invention purpose, the technical scheme that the application adopts is: a kind of concrete electric pole loading-unloading vehicle is used suspender, comprises symmetrical clamp; Clamp adopts the dovetail articulated; The top of clamp is tong arm, and the bottom is the pincers tooth, and the jaw radian that the involutory back of said two pincers teeth forms is corresponding with the outer wall radian of concrete electric pole; The arc length of jaw is greater than 3/4 of concrete electric pole girth, and the difference axle connects suspension ring on the top of two tong arms.
Open for preventing suspender accident in hoisting process; This suspender also comprises safety lock, and safety lock is made up of latch and slotting ring, and the top of latch connects steel wire; The other end of steel wire is fixed therein the top of a tong arm; Slotting ring then is fixed on the side of another pincers tooth, and the length of steel wire equals suspender and is stuck on the concrete electric pole and latch when inserting slotting ring, the length when steel wire is in tensioned state.
For increasing the friction force of jaw and concrete electric pole, preferably at the inboard welding of jaw curved plate, the outer wall radian of the radian of curved plate and concrete electric pole is corresponding.
The beneficial effect of the utility model: owing to adopt technique scheme, saved the process that steel rope is worn, tied, can improve entrucking efficient; Reduce the traffic cost of concrete electric pole, improve electric power circuit and set up speed, reduce the recruitment personnel; Increase benefit, reduce labour intensity, reduce the Employee Security risk.
Description of drawings
Fig. 1 is the structural representation of the application's concrete electric pole loading-unloading vehicle with suspender.
The specific embodiment
Below in conjunction with accompanying drawing the application is further described:
By shown in Figure 1: a kind of concrete electric pole loading-unloading vehicle is used suspender; Comprise symmetrical clamp, clamp adopts the dovetail articulated, and the top of clamp is tong arm 1; The bottom is pincers tooth 2; The jaw radian that said two pincers teeth 2 involutory backs form is corresponding with the outer wall radian of concrete electric pole, and the arc length of jaw is greater than 3/4 of concrete electric pole girth, and the difference axle connects suspension ring 3 on the top of two tong arms 1.
Open for preventing suspender accident in hoisting process; This suspender also comprises safety lock, and safety lock is made up of latch 4 and slotting ring 5, and the top of latch connects steel wire 6; The other end of steel wire 6 is fixed therein the top of a tong arm 1; 5 of slotting rings are fixed on the side of another pincers tooth 2, and the length of steel wire 6 equals suspender and is stuck on the concrete electric pole and latch 4 when inserting slotting rings 5, the length when steel wire 6 is in tensioned state.
For increasing the friction force of jaw and concrete electric pole, preferably at jaw bilateral symmetry welding curved plate 7, the outer wall radian of the radian of curved plate 7 and concrete electric pole is corresponding.
The application's suspender lifting 6-10KV concrete electric pole; Having welded two of 300*300*3 curved plates in pincers tooth inboard, is 600MPa through tested for tensile strength, and yield strength is 355MPa; Percentage elongation is 16%; Bearing the biggest quality is 4.2t, according to three times of calculating of hoisting sling safety factor, satisfies the requirement of the on-the-spot biggest quality (12 meters concrete electric poles) 1.13t fully.
Use the process of this suspender lifting concrete electric pole: be suspended to the steel suspension ring of concrete electric pole loading-unloading vehicle suspender on the hoist lifting hook with steel rope, commander's crane rotates to concrete electric pole top, falls suspension hook, makes an accurate selection of concrete electric pole center of gravity; Pull out the safety lock of suspender, open the pincers tooth of suspender, be clipped in concrete electric pole center of gravity place to the pincers tooth, reach concrete electric pole bottom to the pincers tooth as far as possible; The lifting of commander's crane is observed the pincers tooth and whether is pressed from both sides into concrete electric pole bottom, locking safety lock; Continue lifting, accomplish the entrucking task, unload when hanging; Will pull out safety lock earlier, use crowbar to separate tong arm greater than the concrete pole diameter, concrete electric pole handling process is accomplished in lifting.
