Adjustable weighing and supporting device for construction hoist

Abstract

The invention belongs to the technical field of mechanical building equipment and particularly relates to an adjustable weighing and supporting device for a construction hoist. The adjustable weighing and supporting device comprises a pull rod, a supporting rod, a supporting seat, a pressure sensor, an adjusting device and a bearing standard joint. One end of the pull rod and one end of the supporting rod are each hinged to a supporting seat lug plate corresponding to one end of the supporting seat through a corresponding pin shaft. The end, corresponding to the supporting seat lug plate, of the supporting seat is connected with the adjusting device through a bolt. The adjusting device is arranged between the upper bearing standard joint segment and the adjacent lower bearing standard joint segment. The pressure sensor is arranged on the connecting portions/position of the adjusting device and the upper bearing standard joint body and/or the lower bearing standard joint body. The other end of the pull rod, the other end of the supporting rod and the other end of the supporting seat are connected with corresponding embedded parts fixed to a building. According to the adjustable weighing and supporting device for the construction hoist, a guide rail bracket is divided into multiple segments, the adjustable weighing and supporting device bears all the vertical loads at the specific guide rail bracket height within the range of the upper portion of each segment of the guide rail bracket, the numerical value of the loads can be measured precisely, and if the measured numerical value exceeds the theoretical range, power-off protection is conducted, and the safety of personnel and the equipment is protected.

Description

technical field [0001] The invention belongs to the technical field of construction machinery equipment, in particular to an adjustable weighing support device of a construction elevator. Background technique [0002] The construction hoist is a kind of lifting equipment for vertically transporting personnel and materials in building construction. It is mainly composed of a hanging cage, a transmission device, a guide rail frame, an attachment device and a local protective fence. As the installation height of the guide rail frame of the construction elevator continues to increase, the self-weight of the guide rail frame will also continue to increase, resulting in a large difference in the force of the guide rail frame at different parts, which is especially prominent in super high-rise construction elevators. [0003] The existing solution is to strengthen the guide rail frame of the construction elevator in sections from the bottom to the top, and increase the wall thickne...

Problems solved by technology

[0004] The object of the present invention is to overcome the above-mentioned deficiencies, and provide an adjustable weighing support device for a construction hoist, which divides the guide rail frame into multiple sections, bears the specific height of the upper part of each section of the guide rail frame and all vertical loads within its range, and can accurately measure If the load value exceeds the theoretical range, power-off protection will be performed, thereby eliminating the influence of the vertical load above the supporting device on the guide rail frame below it, protecting the safety of personnel and equipment, and fundamentally solving the problem of super high-rise construction elevator guide rails The problem of excessive self-weight of the frame can be solved, the cost of equipment can be reduced, and the manufacture, delivery and installation of equipment can be greatly simplified
