Abstract

The invention discloses a pair of hoisting calipers, and belongs to the technical field of hoisting devices. The pair of hoisting calipers comprises two hoisting caliper units which are rotationally fixed, wherein each hoisting caliper unit comprises a caliper handle, the caliper handle is inserted into a fixing sleeve, and a hoisting ring is arranged at the upper part of the caliper handle; and clamping jaws are arranged at the bottoms of the caliper handles. The invention further discloses a method for hoisting bars by using the hoisting calipers. The hoisting calipers are simple and compactin structure; with adoption of the method for hoisting the bars by using the hoisting calipers, the bars can be rapidly grabbed, and the hoisting efficiency is guaranteed; and the hoisting calipers can be recycled, so that the cost of a hoisting tool is saved, and meanwhile, the personal injury to an operator in the hoisting process is reduced.

Description

technical field

[0001] The invention belongs to the technical field of lifting devices, and in particular relates to a lifting caliper and a method for lifting and transporting bars. Background technique

[0002] Because it is inconvenient to use ropes and steel cables for lifting bars in a short period of time, and the purchase costs of ropes and steel cables are consumables, the purchase cost will increase virtually, and there will be a risk of fracture after repeated use for a long time.

[0003] Therefore, need to design a kind of device that assists lifting. Contents of the invention

[0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a lifting caliper to assist in lifting, and at the same time, the present invention also provides a method for lifting bars.

[0005] Technical solution: In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A ...

Examples

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, a lifting caliper includes two rotating and fixed lifting caliper units. The lifting caliper unit includes a caliper handle 1 , which is inserted into a fixed sleeve 2 , and a lifting ring 4 is arranged on the top of the caliper handle 1 ; claws 3 are arranged on the bottom of the caliper handle 1 . After mating, the area for lifting the bar 9 is formed between the jaws 3 of the two lifting caliper units.

[0023] Fixing holes 6 are provided on the fixing sleeve 2 , and the two lifting caliper units are fixed through the respective fixing holes 6 .

[0024] The caliper handle 1 is inserted into the upper groove body 5 of the fixed sleeve 2 ; the claw 3 is inserted into the lower groove body 7 of the fixed sleeve 2 .

[0025] Such as figure 2 As shown, a method for hoisting bars by lifting calipers comprises the following steps:
