Description

A kind of lifting construction machinery equipment

technical field

The utility model relates to the technical field of lifting, in particular to a lifting construction mechanical equipment.

Background technique

Construction elevators, also known as freight elevators, are generally larger and have more load than passenger elevators, and most of them are traction-type. There is generally no good decoration inside the freight elevator to avoid damage during cargo transportation, and many elevator door switches are manually controlled. As a commonly used construction equipment, elevators have great potential safety hazards and are prone to danger.

Utility model content

The purpose of this utility model is to provide a lifting construction mechanical equipment to solve the problems raised in the background technology above.

In order to achieve the above purpose, the utility model provides the following technical solutions: a lifting construction machinery equipment, including a pillar and an independent pillar, a winch is installed on one side of the bottom of the pillar, and one end of the hoist is connected by a drive through the inside of the pillar. Steel wire rope, a top platform is installed on the top of the pillar, and the top platform is provided with screw holes relative to the connection of each pillar, the upper surface of the top platform is equipped with a first pulley and a second pulley, and the first pulley and the second pulley The pulleys are all slidably connected with steel wire ropes, and a lifting box is arranged below the top platform, and the top of the lifting box is fixedly connected with lifting lugs, and the lifting lugs are slidably connected with the second pulley through steel wire ropes, and the two sides of the top of the lifting box are Both are fixedly connected with springs, and the springs are installed symmetrically in the center. The end of the springs away from the lifting box is fixedly connected with a pre-tensioning device, and the pre-tensioning device can move on the independent support.

Preferably, the inside of the pillar is a hollow structure, and the number of four pillars is installed on the ground in a square shape.

Preferably, the hoist is installed on the ground, and the connection with the wire rope is located inside the pillar.

Preferably, the pretensioning device moves synchronously with the lifting box.

Preferably, there is a detachable structure between the top platform and the pillar.

Preferably, the number of the independent pillars is two, and they are symmetrically installed on both sides of the lifting box.

Compared with the prior art, the utility model has the beneficial effects that: when the lift suddenly falls, the pre-tensioning device can feel the change of the tension on the spring, and then be stuck on the independent support. Slowly reduce the downward trend of the lift box until it stops. In addition, due to the stretching effect of the spring, it can also prevent people from being hurt by impact. The buffer rubber at the bottom of the lifting box also has a buffering effect, which reduces the occurrence of injuries to a certain extent.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-2, the utility model provides a technical solution: a lifting construction machinery equipment, including a pillar 1 and an independent pillar 12, a hoist 2 is installed on the bottom side of the pillar 1, and one end of the hoist 2 The transmission is connected with a steel wire rope 5 passing through the inside of the pillar 1. A top platform 3 is installed above the pillar 1, and the top platform 3 is provided with screw holes relative to the joints of each pillar. The upper surface of the top platform 3 is equipped with a first One pulley 4 and the second pulley 6, and the first pulley 4 and the second pulley 6 are all slidably connected with the steel wire rope 5, the bottom of the top platform 3 is provided with a lifting box 9, and the top of the lifting box 9 is fixedly connected with a hanging ears 7, and the lifting lugs 7 are slidably connected to the second pulley 6 through the steel wire rope 5, and both sides of the top of the lifting box 9 are fixedly connected with springs 11, and the springs 11 are installed symmetrically in the center, and the springs 11 are far away from the lifting box One end of 9 is fixedly connected with a pretensioning device 8, and the pretensioning device 8 can move on the independent support 12.

Working principle: under the pull of the winch 2, the wire rope 5 is driven to slide on the pulley, and the lifting box 9 is pulled up and down on the first pulley 4 and the second pulley 6 by the wire rope 5. When the lifting box 9 suddenly falls, the pre-tensioning device 8 can feel the change of the tension on the spring 11, and then it will be stuck on the independent support 12. At this time, the lifting box is slowly lowered under the tension of the spring. downward trend until it stops.
