Description

Technical Field

[0001] The utility model relates to the technical field of pipe trench engineering construction equipment, in particular to a tool-type lifting device for a prefabricated cover plate. Background Art

[0002] Precast cover is a building material made of pre-prepared reinforced concrete, usually used to cover wall beams, columns and other structures in concrete. It is a reinforced concrete component.

[0003] After being processed and manufactured by the manufacturer, they are transported to the site for direct installation and fixation, which saves construction time and improves construction efficiency. In order to facilitate the lifting of prefabricated cover plates, they need to be lifted by a lifting device. In the prior art, most lifting devices are unable to firmly clamp and fix prefabricated cover plates of different sizes during use, which can easily cause the prefabricated cover plates to fall during lifting and cause safety accidents. The safety is insufficient, so it is necessary to redesign a prefabricated cover plate tool-type lifting device to address the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a prefabricated cover plate tool-type lifting device.

[0011] Preferably, two movable wheels are fixedly mounted on the lower end surfaces of the two movable plates, and each of the movable wheels is a universal wheel.

[0012] Beneficial effects of the utility model:

[0013] 1. By setting up components such as a double-headed screw, a limit rod and a movable sleeve, when the double-headed screw rotates, it can drive the two movable sleeves to move toward each other through the cooperation with the limit rod, so that the two movable sleeves can drive the two clamping plates to move and approach each other through the cooperation of the connecting plate.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 , a prefabricated cover plate tool-type lifting device comprises two movable plates 1, the upper end surfaces of the two movable plates 1 are jointly fixedly mounted with a support frame 2, the inner wall of the support frame 2 is fixedly mounted with a movable frame 4 through a first lifting mechanism, the first lifting mechanism comprises a first cylinder 3 fixedly mounted on the bottom wall of the support frame 2, the telescopic end of the first cylinder 3 is fixedly connected to the upper end surface of the movable frame 4, the inner wall of the movable frame 4 is rotatably mounted with a double-headed screw 5, and the outer wall of the double-headed screw 5 is threadedly mounted with two movable sleeves 7, a limiting rod 6 is fixedly mounted inside the movable frame 4, the limiting rod 6 slides through the two movable sleeves 7, the limiting rod 6 can limit the movable sleeve 7, so that the movable sleeve 7 can only move axially along the outer wall of the double-headed screw 5, a driving motor 8 connected to the double-headed screw 5 is fixedly mounted on the outer wall of the movable frame 4, and the bottom walls of the two movable sleeves 7 are fixedly mounted with a clamping plate 10 through a connecting mechanism, the connecting mechanism comprises a connecting plate 9 fixedly mounted on the bottom wall of the movable sleeve 7, and the end of the connecting plate 9 is fixedly connected to the outer wall of the clamping plate 10.

[0023] The inner walls of the two clamping plates 10 are fixedly installed with anti-skid pads 11, which are made of rubber. The rubber material has good elasticity and softness, which enables it to form a closer contact between the surface and the object, thereby increasing friction and improving the friction coefficient. Two moving wheels 12 are fixedly installed on the lower end surfaces of the two movable plates 1. Each moving wheel 12 is a universal wheel. The convenience of moving the two movable plates 1 can be increased by cooperating with multiple universal wheels. Two support plates 14 are fixedly installed on the lower end surfaces of the two movable plates 1 through a second lifting mechanism. The second lifting mechanism includes a second cylinder 13 fixedly installed on the bottom wall of the movable plate 1, and the telescopic end of the second cylinder 13 is fixedly connected to the upper end surface of the support plate 14.

[0024] When the utility model is used, the two moving plates 1 can be conveniently moved by the cooperation of the multiple moving wheels 12, so that the prefabricated cover plate is between the two moving plates 1, and then the second cylinder 13 can drive the support plate 14 to move downward, so that the multiple support plates 14 support the two moving plates 1, thereby ensuring the stability when the prefabricated cover plate is lifted, and through the support of the multiple support plates 14, the moving wheels 12 are not in contact with the ground, thereby avoiding the moving wheels 12 from bearing weight, reducing damage to the moving wheels 12, and increasing their service life;

[0025] When the prefabricated cover is lifted, the moving frame 4 is driven up and down by the first cylinder 3 inside the support frame 2, and the driving motor 8 drives the double-headed screw 5 to rotate. When the double-headed screw 5 rotates, it can drive the two moving sleeves 7 to move toward each other through the cooperation with the limit rod 6, so that the two moving sleeves 7 can drive the two clamping plates 10 to move and approach each other through the cooperation of the connecting plate 9, and clamp the prefabricated cover through the anti-slip pad 11 on the inner wall of the clamping plate 10. Driven by the double-headed screw 5, the distance between the two clamping plates 10 can be conveniently adjusted, so that the two clamping plates 10 can clamp prefabricated cover plates of different sizes, and the rubber anti-slip pad 11 can increase the friction with the outer wall of the prefabricated cover, thereby increasing the reliability of clamping to prevent the prefabricated cover from falling during lifting.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
