Problems solved by technology

In the factory, as long as there is a quilting structure for the installation bracket and the lifting chamber, it is convenient for technicians to carry out maintenance. However, because the current lifting equipment is not equipped with safety protection devices, when the cargo carrying platform is in the process of descending, if the cargo carrying platform There are technicians below who are maintaining the lifting equipment, which will be extremely dangerous for the technicians

Embodiment 1

[0022] The cargo lifting device with safety alarm function includes installation brackets arranged in the vertical direction, such as figure 1 As shown, the cargo lifting platform 20, the power mechanism and the track 10 arranged in the vertical direction are installed on the mounting bracket, and the left and right sides of the mounting bracket are provided with rails 10, and the rails 10 are arranged symmetrically along the vertical plane. The cargo lifting platform 20 is a quilted frame structure to reduce the weight of the cargo lifting platform 20. The cargo lifting platform 20 is slidingly connected with the mounting bracket through the rail 10, and the rail 10 has a limiting effect on the cargo lifting device to prevent the cargo lifting platform 20 from deviating from the installation. Bracket; In the present embodiment, the power mechanism adopts a winch, and the winch is installed at the bottom of the mounting bracket, and the winch is used as a power output structure...

Embodiment 2

[0029] The difference between Embodiment 2 and Embodiment 1 is that, as image 3 As shown, in the second embodiment, the cylinder body 21 is arranged horizontally, and the end face of the wedge block 22 protruding from one end of the opening of the cylinder body 21 is set as a wedge surface, and the wedge surface is set downward, and the angle between the wedge surface and the horizontal plane is 45° . When the cargo lifting platform 20 goes down, when the block 11 cooperates with the wedge surface of the wedge 22, the wedge 22 will be pressed back into the cylinder 21, so that the wedge 22 can reciprocally slide in the cylinder 21.

Abstract

The invention relates to lifting equipment, and particularly discloses a cargo lifting device with a safety alarm function. The cargo lifting device comprises a mounting support and a cargo lifting platform, the cargo lifting platform is in sliding connection with the mounting support through a rail, a plurality of stop blocks are arranged on the rail, a gas pressing structure, a gas tank and a pneumatic brake structure are arranged on the side face of the cargo lifting platform, wherein the gas pressure structure comprises a cylinder body and a wedge block which is arranged in the cylinder body and can slide, a pressure spring abutting against the wedge block is arranged in the cylinder body, an air inlet one-way valve and an air outlet one-way valve are arranged at the bottom of the cylinder body, the air outlet one-way valve is connected with the gas tank, an infrared sensor which is electrically connected with a controller is arranged at the bottom of the cargo lifting platform, the pneumatic brake structure comprises an air chamber and a brake block, the brake block can extend out of the air chamber and can be matched with the stop blocks, a tension spring is arranged inside the air chamber and is connected with the brake block, the air tank is connected with the air chamber through an electromagnetic valve, and the electromagnetic valve is electrically connected with thecontroller. In the descending process of the cargo lifting platform, the pneumatic brake structure has an emergency braking function on the cargo lifting platform.

Description

technical field [0001] The invention relates to lifting equipment, in particular to a cargo lifting device with a safety alarm function. Background technique [0002] Lifting equipment is one of the most commonly used equipment in the field of industrial production. In industrial production, lifting equipment plays the role of transporting goods in the vertical direction. Common lifting equipment includes mounting brackets or lifting chambers. The cargo-carrying platform is equipped with rails for the cargo-carrying platform to slide; its power device is mainly a hoist, and the hoist lifts the cargo-carrying platform or lowers the cargo-carrying platform through a sling. In the factory, as long as there is a quilting structure for the installation bracket and the lifting chamber, it is convenient for technicians to carry out maintenance. However, because the current lifting equipment is not equipped with safety protection devices, when the cargo carrying platform is in the p...
