Description

Lifting fixture for hydraulic cylinder

technical field

The utility model relates to a clamp, in particular to a lifting clamp for a hydraulic oil cylinder cylinder used for hoisting a cylinder cylinder of a hydraulic cylinder.

Background technique

A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. At present, in the production and manufacturing process of hydraulic cylinders, the cylinder barrels are bound and fixed with steel wire ropes, and then hoisted by driving. However, the stability of binding and fixing with steel wire ropes is relatively poor, and there is a potential safety hazard of the cylinder barrel falling. And, the process of taking off the cylinder barrel in the way of wire rope binding is loaded down with trivial details.

Utility model content

The technical problem to be solved by the utility model is to provide a hoisting fixture for a cylinder barrel of a hydraulic oil cylinder. The hoisting fixture has good stability and avoids potential safety hazards.

In order to solve the above problems, the following technical solutions are provided:

The utility model is characterized in that the lifting jig for the cylinder barrel of the hydraulic oil cylinder comprises a horizontally arranged bottom plate, a vertically arranged support tube is arranged on the upper surface of the bottom plate, and lifting lugs are arranged on the top of the support tube. The upper part of the support tube has a horizontally arranged support beam, and the side wall of the support tube corresponding to the support beam is symmetrically provided with vertical slots, and the two ends of the support beam extend through the corresponding vertical slots to the bottom of the support tube respectively. On both sides, the supporting beam and the vertical channel are in an upward and downward sliding manner. The bottom part of the support beam located in the support tube is connected with a vertically downwardly arranged connecting rod. The connecting rod and the supporting tube are in a sliding fit. The bottom plate corresponding to the connecting rod has a relief opening. The lower end of the connecting rod passes through Let the opening protrude below the base plate with a weight attached to the lower end of the connecting rod.

Wherein, the bottom plates corresponding to the two ends of the supporting beam are provided with limiting platforms.

Outer rims at both ends of the support beam are uniformly connected with outturned edges protruding from the bottom.

There is a pit for accommodating the weight on the lower surface of the bottom plate.

Adopting the above scheme has the following advantages:

Since the lifting fixture for the hydraulic oil cylinder of the utility model includes a bottom plate, there is a support tube on the upper surface of the bottom plate, the top of the support tube is provided with lifting lugs, the upper part of the support tube is provided with a support beam, and the side wall of the support tube corresponding to the support beam is The upper part is symmetrically provided with vertical slots, and the two ends of the support beam extend out to both sides of the support tube through the corresponding vertical slots, and the bottom of the support beam inside the support tube is connected with a connecting rod, which corresponds to There is a relief opening on the base plate, and the lower end of the connecting rod is fixed with a weight. When in use, first place the cylinder vertically on the bottom plate under the support beam; then, use the crane to lift the fixture through the lifting lugs, and under the action of the gravity of the weight, the support beam is pressed on the cylinder, and the cylinder is adjusted. Fixed; finally, after hoisting to the destination and putting down the hoisting fixture, under the ground constraints, the connecting rod pushes the support beam up to leave the cylinder, and the cylinder can be removed. This hoisting fixture uses the support beam to restrict the cylinder. Compared with the background technology of winding steel wire ropes, it has better stability, avoids potential safety hazards, and the process of removing the cylinder is convenient.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Fig. 1, the feature of the hoisting fixture for the cylinder barrel of the hydraulic oil cylinder of the present invention is that it includes a bottom plate 1 arranged in a horizontal manner. There are lugs 5. The upper part of the support tube 8 has a support beam 4 arranged horizontally, and the side wall of the support tube 8 corresponding to the support beam 4 is symmetrically provided with a vertical channel 6, and the two ends of the support beam 4 pass through the corresponding vertical channel respectively. 6 protrudes to both sides of the support pipe 8, and the support beam 4 and the vertical through groove 6 are fitted in an up and down sliding manner. The bottom of the support beam 4 in the support tube 8 is connected with a vertically downwardly arranged connecting rod 7, and the connecting rod 7 and the supporting tube 8 are in a sliding fit, and the bottom plate 1 corresponding to the connecting rod 7 has a relief opening. The lower end of the connecting rod 7 passes through the opening of the base plate 1 and protrudes under the base plate 1 , and the lower end of the connecting rod 7 is fixed with a weight 10 .

In order to further limit the cylinder barrel, there are limit platforms 2 on the bottom plates 1 corresponding to the two ends of the support beam 4 . Outer edges at both ends of the support beam 4 are integrally connected with outwardly extending flanges 3 .

There is a pit 9 for accommodating a weight 10 on the lower surface of the bottom plate 1 .

During use, the cylinder barrel 11 is placed vertically on the bottom plate 1 below the support beam 4, and the mouth of the cylinder barrel 11 is sleeved on the limit platform 2. Next, the jig is hoisted by the crane through the lifting lug 5, and under the action of the gravity of the weight 10, the support beam 4 is pressed on the cylinder barrel to fix the cylinder barrel 11, as shown in FIG. 2 . Finally, after hoisting to the destination and putting down the hoisting fixture, the connecting rod 7 pushes the support beam 4 upwards under the constraints of the ground to leave the cylinder 11, and the cylinder 11 can be removed.
