DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1-5 , this embodiment provides a tower crane climbing assistance device, which includes a tower crane bracket 13, a tower crane platform 11 fixedly connected to the tower crane bracket 13, and a climbing ladder 14 installed on the tower crane platform 11. A steel cable 18 is installed on the tower crane platform 11. One end of the steel cable 18 is fixedly connected to a safety belt 15, and the other end of the steel cable 18 is installed with a counterweight 19. A fastening assembly 17 is installed on the tower crane platform 11. A pulley block 20 is installed in the fastening assembly 17, and the middle part of the steel cable 18 is installed on the pulley block 20. A speed limiter 21 is installed in the fastening assembly 17.

[0023] Through the connection of the pulley block 20 and the steel cable 18, the counterweight 19 can play a role in assisting the climber wearing the safety belt 15 to climb. Due to the weight of the counterweight 19, the climber can be more labor-saving during the climbing process. Through the speed limiter 21, when the steel cable 18 falls rapidly, the steel cable 18 can be clamped to avoid the occurrence of a falling accident caused by slipping off.

[0024] An electric motor for pulling the steel cable 18 on one side of the counterweight 19 upward is provided in the fastening assembly 17.

[0025] Among them, both the pulley block 20 and the speed limiter 21 are common devices.

[0026] Among them, when no liquid is injected into the counterweight 19, its basic weight is 60 kg.

[0027] An inlet 29 and an outlet 30 are provided on the counterweight 19. A circulation assembly 23 for connecting the inlet 29 and the outlet 30 is installed on the tower crane platform 11. Liquid is injected into and / or discharged from the counterweight 18 through the circulation assembly 23. A cavity for water injection is provided inside the counterweight 19. A protective housing 12 is provided at the lower part of the tower crane platform 11. The counterweight 19 is slidably connected to the protective housing 12 along the height direction of the tower crane bracket 13. The circulation assembly 23 includes a water tank 28 provided in the protective housing 12. A water outlet pipe 24 extending to the inlet 29 is communicated in the water tank 28. A water pump 22 is installed on the water tank 28 at one end of the water outlet pipe 24.

[0028] Increasing the weight of the counterweight 19:

[0029] It is necessary to inject water into the interior of the counterweight 19 through the water inlet 29. When injecting water, first use the motor to pull the counterweight 19 to the top, insert one end of the water outlet pipe 24 into the water inlet 29, and start the water pump 22 to inject water into the cavity.

[0030] A rotating plate 26 for supporting the counterweight 19 is rotatably connected inside the protective housing 12. A connecting pipe 27 for connecting the water outlet 30 is installed on the rotating plate 26. The connecting pipe 27 is communicated with the water tank 28 through a water inlet pipe 25. A first one-way valve is provided in the water inlet 29, a flap valve is provided in the water outlet 30, and a second one-way valve is installed in the connecting pipe 27.

[0031] Reducing the weight of the counterweight 19:

[0032] It is necessary to drain the water in the counterweight 19 through the water outlet 30. While turning off the motor, turn the rotating plate 26 to an angle parallel to the bottom surface of the tower crane platform 11. And there is a self-locking structure in the rotating plate 26, which will not automatically open without rotation. At this time, the water outlet 30 will be inserted into the connecting pipe 27, and through the connecting pipe 27 and the water inlet pipe 25, it will flow into the water tank 28.

[0033] Due to the action of the first one-way valve and the flap valve, the water in the cavity will not flow out. And due to the action of the second one-way valve, when the rotating plate 26 rotates downward, the water in the connecting pipe 27 will not flow out either.

[0034] Embodiment 2

[0035] Please refer to Figure 1 and Figure 5 , this embodiment provides a tower crane climbing assistance device. A cavity for injecting water is provided inside the counterweight 19. A protective housing 12 is provided below the tower crane platform 11. The counterweight 19 is slidably connected inside the protective housing 12 along the height direction of the tower crane support 13.

[0036] In this embodiment, in the cavity of the counterweight 19 for injecting water, the water can be replaced with any kind of liquid with stable properties, and this liquid cannot be corrosive to the counterweight 19. By adding or draining the liquid, the weight inside the counterweight 19 can also be increased, achieving the effect of balancing the weight of the climber.

[0037] The maximum volume of liquid that can be injected into the cavity of the counterweight 19 is 40L.

[0038] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
