Description

Technical Field

[0001] The utility model relates to the technical field of lifting, in particular to a construction lifting machine gangway. Background Art

[0002] Construction elevators are mainly used in various types of high-rise and super-high-rise buildings in cities. Since there is a certain gap between the construction elevator and the waiting platform on each floor, in order to facilitate workers to get on and off the construction elevator and transport goods, workers usually lay a flat plate between the construction elevator and the waiting platform after the construction elevator stops and the cage door is opened to facilitate passage. After use, the flat plate is manually withdrawn so that the construction elevator can close the cage door to continue operating. However, manually laying the flat plate after the construction elevator stops opening the door and manually retracting the flat plate before the construction elevator operates requires a lot of time to lay and retract the flat plate, which reduces the transportation efficiency of the elevator and consumes manpower to lay and retract the flat plate. Utility Model Content

[0003] The utility model aims to provide a construction elevator gangway to solve the technical problems that there is a gap between a traditional construction elevator and the waiting platform on each floor, and that the flat plate laid in the gap needs to be manually laid and withdrawn, which reduces the transportation efficiency of the elevator and wastes manpower.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a construction elevator gangplank, the construction elevator gangplank comprising:

[0005] A springboard body, the bottom of which is hinged to the floor of the construction elevator, and the springboard body is located inside the construction elevator on one side close to the cage door of the construction elevator;

[0006] The pressure rod is U-shaped, and both ends of the pressure rod are connected to the lower half door of the construction elevator cage door through rivets, and the springboard body is located between the pressure rod and the lower half door.

[0007] In one embodiment, a roller is sleeved on the pressure rod, and the roller is rotatably arranged on the pressure rod, and the roller is located at a position on the pressure rod that contacts the springboard body.

[0008] In one embodiment, a blocking portion extending toward the interior of the construction elevator is provided on the top of the springboard body.

[0009] In one embodiment, a side of the springboard body close to the interior of the construction elevator is provided with an anti-slip layer.

[0010] In one embodiment, the pressure rod comprises:

[0011] A guide section, wherein the guide section is in a straight line shape, and the roller is sleeved on the guide section, and the width of the guide section is greater than the width of the springboard body;

[0012] A connecting section is arranged at both ends of the guiding section, and the ends of the connecting section are connected to the lower half door of the cage door of the construction elevator through the rivets.

[0013] In one embodiment, an elastic gasket is provided on a side of the springboard body away from the interior of the construction elevator.

[0014] One or more of the above technical solutions in the embodiments of the present utility model have at least the following technical effects or advantages:

[0015] The construction elevator springboard provided by the embodiment of the utility model is hinged and fixed to the floor on one side of the cage door in the construction elevator by the bottom of the springboard body, and a pressure rod is set to cover the pressure rod on the springboard body, and at the same time, the two ends of the pressure rod are connected to the lower half door of the cage door of the construction elevator by rivets, so that when the cage door of the elevator is opened (the cage door of the construction elevator includes an upper half door and a lower half door, and the opening method is that the upper half door slides upward and the lower half door slides downward, and the existing construction elevator usually adopts electric drive to open and close the cage door), the lower half door slides downward and opens, which will drive the pressure rod to move downward until the lower half door is fully opened. During this process, the springboard body will be tilted and fallen toward the waiting platform under the traction of the pressure rod, so that the springboard body is flat between the construction elevator and the waiting platform, covering the gap between the two, so as to facilitate workers or goods to enter and exit the construction elevator. When the construction elevator door is closed, the lower half door slides upward, and at this time the lower half door gives an upward force to the main body of the springboard, so that the main body of the springboard rotates upward from the flat state to the upright state, and the pressure rod restricts the main body of the springboard to prevent the main body of the springboard from falling to the floor of the construction elevator. Therefore, the laying and folding of the main body of the springboard are carried out synchronously with the opening and closing of the lower half door, so there is no need for manual laying and folding, thereby improving the transportation efficiency of the elevator and saving the manpower for laying and folding the flat plate.

[0016] In addition, laying the main body of the springboard while opening the cage door can avoid accidents in which workers forget to lay the flat plate and walk out of the construction elevator directly after the cage door is opened, causing the workers to fall from the gap between the construction elevator and the waiting platform.

[0028] See also Figures 1 to 3 The embodiment of the present application provides a construction elevator springboard, including a pressure rod 2 and a springboard body 1, wherein the bottom of the springboard body 1 is hinged to the floor 41 of the construction elevator, and the springboard body 1 is located inside the construction elevator on one side close to the construction elevator cage door; the pressure rod 2 is U-shaped, and both ends of the pressure rod 2 are connected to the lower half door 42 of the construction elevator cage door through rivets 3, and the springboard body 1 is located between the pressure rod 2 and the lower half door 42.

[0029] The construction elevator springboard provided by the utility model is hinged and fixed to the floor 41 on one side of the cage door in the construction elevator by the bottom of the springboard body 1, and the pressure rod 2 is set, the pressure rod 2 is sleeved on the springboard body 1, and the two ends of the pressure rod 2 are connected to the lower half door 42 of the construction elevator cage door through rivets 3, so that when the elevator cage door is opened (the cage door of the construction elevator includes an upper half door 43 and a lower half door 42, and the opening method is that the upper half door 43 slides upward and the lower half door 42 slides downward, and the existing construction elevator usually adopts electric drive to open and close the cage door), the lower half door 42 slides downward to open and drives the pressure rod 2 to move downward until the lower half door 42 is fully opened. In this process, the springboard body 1 is driven by the pressure rod 2 to tilt and fall toward the waiting platform 5 (such as Figure 3 The main body 1 of the springboard is laid flat between the construction elevator and the waiting platform 5, covering the gap between the two, so that workers or goods can enter and exit the construction elevator. When the construction elevator door is closed, the lower half door 42 slides upward, and the lower half door 42 exerts an upward force on the main body 1 of the springboard, so that the main body 1 of the springboard rotates upward from the flat state to the erected state (as shown in the figure). Figure 2In the state shown in FIG. 1 , the pressure rod 2 limits the springboard body 1 to prevent the springboard body 1 from falling toward the floor 41 of the construction elevator. Therefore, the laying and folding of the springboard body 1 are performed synchronously with the opening and closing of the lower half door 42, so there is no need for manual laying and folding, thereby improving the transportation efficiency of the elevator and saving the manpower for laying and folding the flat plate.

[0030] In addition, laying the springboard body 1 while the cage door is open can avoid accidents in which workers forget to lay the slab and walk out of the construction elevator directly after the cage door is opened, causing the workers to fall from the gap between the construction elevator and the waiting platform 5.

The roller 6 can greatly reduce the friction between the pressure rod 2 and the springboard body 1, reduce the wear of the pressure rod 2 and the springboard body 1, and thus increase the service life of the pressure rod 2.

[0032] In one embodiment, a blocking portion 11 extending toward the inside of the construction elevator is provided on the top of the springboard body 1. The blocking portion 11 can be used to hook the pressure rod 2 to prevent the pressure rod 2 from detaching from the springboard body 1.

[0033] In one embodiment, a non-slip layer is provided on one side of the main body 1 of the springboard close to the inside of the construction hoist. The non-slip layer can be a groove or die-cast pattern, etc. By providing the non-slip layer, the slipping phenomenon of the main body 1 of the springboard is reduced, and the traffic safety is improved.

[0034] like Figure 4 As shown, in one embodiment, the pressure rod 2 includes a connecting section 22 and a guide section 21. The guide section 21 is in a straight line shape, and the roller 6 is sleeved on the guide section 21, and the width of the guide section 21 is greater than the width of the springboard body 1; the connecting section 22 is arranged at both ends of the guide section 21, and the end of the connecting section 22 is connected to the lower half door 42 of the construction elevator cage door through the rivet 3.

[0035] In one embodiment, an elastic gasket is provided on the side of the springboard body 1 away from the inside of the construction elevator. The elastic gasket can be a rubber gasket, which can play a buffering role, thereby reducing the impact force between the springboard body 1 and the waiting platform 5 during the process of lowering and leveling, and protecting the springboard body 1.
