Description

Technical Field

[0001] The utility model relates to the field of building hoisting machinery, in particular to an intelligent construction hoist passage detection device. Background Art

[0002] In today's construction industry, with the shortage of professional human resources and the increasing labor costs, intelligent control technology has become an important technical development direction for construction elevators in the future. Especially for modern construction, the use of intelligent construction elevators is particularly important. It can greatly improve productivity and save labor time. People's comprehensive requirements for the efficiency, safety, performance, intelligence, labor costs, maintenance and other aspects of elevators are also getting higher and higher;

[0003] Some existing construction elevators still need to be manually operated by passengers. This method requires professional operation and is inefficient. It brings a lot of inconvenience to people and wastes a lot of manpower and material resources. The new intelligent construction elevator can automatically run at the same level, but automatic operation also brings many safety issues. Therefore, we are required to develop a channel detection device to ensure that if there are interference objects during the operation of the unmanned intelligent construction elevator, the intelligent construction elevator can stop steadily, reduce damage to the construction elevator and ensure the safety of passengers.

[0034] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0035] Please refer to Figures 1 to 3 The utility model provides an intelligent construction elevator channel detection device, including a guardrail 1, a channel detection collision rod 2, an electrical limit switch 3, a limit support plate 5, a collision rod support plate 6, a torsion spring 7 and a top foot shaft sleeve 8;

[0036] The limiting support plate 5 is fixed on the guardrail 1;

[0037] The electrical limit switch 3 is installed on the limit support plate 5;

[0038] The collision rod support plate 6 is fixed on the guardrail 1;

[0039] The channel detection collision rod 2 is fixedly mounted with a connection plate 9 which is symmetrically arranged on both sides, and the ends of two groups of connection plates 9 away from the channel detection collision rod 2 are rotatably connected to the limit support plate 5 and the collision rod support plate 6 respectively;

[0040] The top foot sleeve 8 is fixed on the collision rod support plate 6;

[0041] The torsion spring 7 is installed on the collision rod support plate 6, one end of the torsion spring 7 is connected to the corresponding connecting plate 9, and the other end of the torsion spring 7 is connected to the top foot sleeve 8;

[0042] When in use, the guardrail 1 can be raised and lowered with the elevator in the passage. When the elevator is running upward, if there is a foreign object extending out of the floor and blocking its running passage, the protruding object will cause the passage detection collision rod 2 to move downward, and the passage detection collision rod 2 touches the trigger rod of the electrical limit switch 3 to cause it to operate, and the elevator stops running. When the foreign object is no longer touching, under the action of the elastic force of the torsion spring 7, the passage detection collision rod 2 returns to its original state, and at the same time, the passage detection collision rod 2 no longer touches the position of the electrical limit switch 3, and the elevator returns to normal.

[0043] In this embodiment, a rain cover 4 is provided on the limit support plate 5, and the rain cover 4 covers the electrical limit switch 3 inside. The rain cover 4 protects the electrical limit switch 3 and prevents the electrical limit switch 3 from being damaged by rain.

[0044] In this embodiment, the channel detection collision rod 2 is arranged above the switch key of the electrical limit switch 3. When the channel detection collision rod 2 moves downward, the closing instruction of the electrical limit switch 3 is triggered.

[0045] In this embodiment, the electrical limit switch 3 is a travel limit switch.

[0046] In this embodiment, the channel detection collision rod 2 is a hollow welded pipe, the length of the channel detection collision rod 2 is greater than the width of the construction elevator cage, and the channel detection collision rod 2 is located above the guardrail 1;

[0047] The working principle of the utility model is as follows:

[0048] The guardrail 1 can be raised and lowered with the elevator in the passage. When the elevator is running upward, if there is a foreign object extending out of the floor and blocking its running passage, the protruding object will cause the passage detection collision rod 2 to move downward, and the passage detection collision rod 2 touches the trigger rod of the electrical limit switch 3 to make it move, and the elevator stops running. When the foreign object is no longer touching, under the action of the elastic force of the torsion spring 7, the passage detection collision rod 2 returns to its original state, and at the same time, the passage detection collision rod 2 no longer touches the position of the electrical limit switch 3, and the elevator returns to normal.
