Description

Technical Field

[0001] The utility model relates to the field of towers, in particular to a tower with a self-locking elevator guardrail door. Background Art

[0002] The construction tower is a piece of equipment that is required for high-rise buildings. Transport elevators are installed on the construction tower to transport materials and personnel in high-rise buildings. At present, there are still certain problems in the use of traditional construction towers. For example, in order to ensure safety, guardrail doors are generally installed at the elevator entrance of the construction tower. However, the traditional construction tower lacks a self-locking structure for the guardrail door. When the elevator passes through the construction tower and rises to a high altitude, its guardrail door can still be opened. When outsiders are not paying attention, it is easy to be dangerous and cause personal accidents. In addition, the traditional tower is composed of multiple tower components combined with each other. The tower components are fixed with bolts or fixings. When the assembled tower is high, the force on the corresponding bolts and fixings will increase, the wear of the bolts and fixings will increase, and it is easy to break or loosen, and the stability is poor. Utility Model Content

[0003] The utility model aims to provide a tower with a self-locking elevator guardrail door, which has the advantages of a self-locking guardrail door and strong stability.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions: a tower with a self-locking elevator guardrail door, comprising a base, a first tower, a second tower and a third tower are respectively arranged on the top of the base, a first steel wire rope is fixedly installed between the first tower and the second tower through a fixing member, a second steel wire rope is fixedly installed between the second tower and the third tower through a fixing member, a protective door is arranged on the front of the first tower, a buffer plate is arranged on the top of the base, a return spring is arranged between the buffer plate and the base, a connecting block is bolted to the buffer plate, a locking block is bolted to the top of the connecting block, and a locking groove for use with the locking block is opened at the bottom of the protective door.

[0005] By adopting the above technical scheme, the utility model installs a buffer plate on the top of the base and a protective door on the first tower. When the elevator inside the tower falls on the buffer plate, the buffer plate sinks downward, and the buffer plate drives the connecting block to fall, and then drives the locking block to separate from the locking groove, so that the protective door can be opened. Conversely, under the action of the reset spring, the connecting block on the buffer plate drives the locking block to be stuck in the locking groove, so as to achieve the purpose of automatic locking and prevent the protective door from opening when the elevator rises. Eight first steel wire ropes are installed between the first tower and the second tower, and four second steel wire ropes are installed between the second tower and the third tower. The installation stability between the first tower and the second tower and between the second tower and the third tower can be improved, the stress on the bolts or fixings between the tower assemblies can be reduced, and the safety can be improved.

[0006] The utility model is further configured as follows: a step is bolted to the top of the base, and the step is used in conjunction with the protective door.

[0007] The technical solution is adopted to facilitate the staff to pedal.

[0008] The utility model is further configured as follows: both ends of the reset spring are bolted with mounting plates through fixing members, and the two mounting plates are bolted to the buffer plate and the base respectively.

[0009] The above technical solution is adopted to facilitate the limiting of the return spring.

[0010] The utility model is further configured as follows: a guide block is bolted to the bottom of the buffer plate, and a guide groove used in conjunction with the guide block is provided on the top of the base.

[0011] The buffer plate is limited by adopting the above technical solution.

[0012] The utility model is further configured as follows: a top plate is bolted to the top of the third tower.

[0013] The above technical solution is adopted to facilitate the installation of the elevator.

[0014] The utility model is further configured as follows: a pile body is bolted to the bottom of the base, and the number of the pile bodies is four.

[0015] The above technical solution is adopted to facilitate the fixing of the base.

[0016] The utility model is further configured as follows: a crossbeam is bolted to the front of the first tower, a sliding block is bolted to the top of the protective door, and a sliding groove used in conjunction with the sliding block is provided at the bottom of the crossbeam.

[0017] The above technical solution is adopted to slide and limit the protective door.

[0018] The utility model is further configured that: the first tower and the base, the first tower and the second tower, and the second tower and the third tower are all connected by bolt threads.

[0019] By adopting the above technical solution, the first tower and the base, the first tower and the second tower, and the second tower and the third tower are tightly limited.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model has a buffer plate installed on the top of the base, and a protective door installed on the first tower. When the elevator inside the tower falls on the buffer plate, the buffer plate sinks downward, and the buffer plate drives the connecting block to fall, thereby driving the locking block to separate from the locking groove, so that the protective door can be opened. Conversely, under the action of the reset spring, the connecting block on the buffer plate drives the locking block to be stuck in the locking groove, so as to achieve the purpose of automatic locking, and prevent the protective door from being opened when the elevator rises;

[0022] 2. The utility model installs eight first steel ropes between the first tower and the second tower, and four second steel ropes between the second tower and the third tower, so as to improve the installation stability between the first tower and the second tower and between the second tower and the third tower, reduce the stress on the bolts or fixings between the tower assemblies, and improve safety.
