Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding components or accessories, in particular to an automatic lubrication system for a climbing frame gear rack. Background Art

[0002] A climbing frame is a special type of scaffolding used in the construction process. It can be understood as a special type of construction elevator, but its cabin is not a box located inside the building but a multi-story frame surrounding the entire building.

[0003] The climbing frame is either climbed by gear rack or chain. In the climbing frame that adopts gear rack meshing, the impact and friction resistance during the meshing process are relatively large. If it is not effectively lubricated, the equipment will wear quickly and there will be extra energy consumption.

[0004] Normally, the gear structure is lubricated by a circulating lubrication system in a closed space, and a circulating oil pump is used to repeatedly lubricate the meshing position. However, the rack of the climbing frame is very long, and it is impossible to put the gear and rack in a closed box. Therefore, the gear rack of the climbing frame is in an open space, and it is impossible to use a circulating oil pump for automatic lubrication. In actual construction, the lubrication of the gear rack of the climbing frame is intermittent, that is, oiling and lubrication are performed during maintenance.

[0005] However, the loss of lubricating oil in an open environment is very large, because the structure of the rack and pinion of the climbing frame is very conducive to the loss of lubricating oil. If grease is used for lubrication, there will be another problem, that is, in a dusty environment such as a construction site, the grease and dust will form sludge together. Therefore, the lubrication effect of the rack and pinion of the climbing frame is not good (the lubricating oil cannot be replenished in time during operation) and additional manpower is required. Utility Model Content

[0006] The utility model provides an automatic lubrication system for a climbing frame gear rack.

[0007] The technical problem to be solved is that the lubrication effect of the gear rack of the climbing frame is poor (the lubricating oil cannot be replenished in time during operation) and additional manpower is required.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions: an automatic lubrication system for a climbing frame gear rack, comprising an oil pot provided on a climber of the climbing frame and filled with lubricating oil, a mounting bracket for fixing the oil pot on the climber, an oil pipe extending from the oil pot to the meshing position of the gear and the rack of the climber, a brush inserted at the oil pipe opening and resting on the rack, and an extruder provided on the oil pot and used to control the oil discharge rate of the oil pot;

[0009] The oil pipe is a hard pipe, which extends from the oil pot, bends and extends perpendicularly to the gear to the meshing position of the gear and the rack.

[0010] Furthermore, the oil pot is a soft pot made of a corrugated hose with sealed ends, and the extruder is a screw arranged on the top of the oil pot. One end of the screw is screwed on the mounting bracket, and the other end extends along the central axis of the corrugated hose and is supported on the top of the oil pot. During use, the oil pot is filled with air that accounts for at least one third of the total volume.

[0011] Furthermore, the mounting bracket includes two bridge-shaped brackets that span the racks and are anchored on the climber, and a mounting plate that is parallel to the racks and has both ends fixedly connected to the bridge-shaped brackets, and the oil pot is fixed on the mounting plate.

[0012] Furthermore, the two ends of the oil pot are respectively provided with top covers buckled on the ends, and among the two top covers, the top cover at the upper end is connected as a whole with the screw rod, and the top cover at the lower end is fixed on the mounting plate, and the oil pipe extends into the oil pot from the top cover at the lower end.

[0013] Furthermore, a sleeve ring is sleeved on the middle part of the oil pot, which is in clearance fit with the oil pot and is used to prevent the oil pot from being distorted during the extrusion process, and the sleeve ring is fixed on the mounting plate.

[0014] Furthermore, the brush is a carbon silicon nylon brush in the shape of a brush head and is detachably inserted into the opening of the oil pipe.

[0015] Compared with the prior art, the automatic lubrication system for the climbing frame gear rack of the utility model has the following beneficial effects:

[0016] In the utility model, an oil pot with an extruder is installed on the climber of the climbing frame, and the lubricating oil is introduced to the meshing position of the gear rack by using an oil pipe and a brush. During the lifting process of the climbing frame, the lubricating oil is continuously brushed to the meshing position of the gear rack, thereby realizing automatic continuous lubrication, and solving the problem that the lubricating oil cannot be replenished in time during the operation of the climbing frame.

[0019] In the figure, 1-climber, 2-climbing rack, 3-mounting bracket, 4-oil pot, 5-oil pipe, 6-brush, 7-extruder. DETAILED DESCRIPTION

[0020] like Figure 1-2As shown, an automatic lubrication system for a climbing frame gear rack comprises an oil pot 4 provided on a climber 1 of the climbing frame and filled with lubricating oil, a mounting bracket 3 for fixing the oil pot 4 on the climber 1, an oil pipe 5 extending from the oil pot 4 to the meshing position of the gear and the rack of the climber 1, a brush 6 inserted into the opening of the oil pipe 5 and resting on the rack, and an extruder 7 provided on the oil pot 4 and used for controlling the oil output rate of the oil pot 4;

[0021] The climber 1 here is a structure that provides power in the climbing frame and moves up and down along the rack. The brush 6 is used here because the position of the climber 1 vibrates greatly during use. If a valve or other structure is used to control the opening and closing, it is easy to insert the hard component into the meshing position, causing it to be clamped and affecting the operation of the climbing frame. The brush 6 is used here, so that even if it is clamped, it will not be damaged and will not affect the operation of the climbing frame.

[0022] The oil pipe 5 is a hard pipe, which extends from the oil pot 4, bends and extends perpendicularly to the gear to the meshing position of the gear and the rack.

[0023] The oil pipe 5 must not be a hose, otherwise it may deviate from the position requiring lubrication due to vibration during operation.

[0024] The oil pot 4 is a soft pot made of a corrugated hose with sealed ends. The extruder 7 is a screw arranged on the top of the oil pot 4. One end of the screw is screwed to an ear plate of the mounting bracket 3, and the other end extends along the central axis of the corrugated hose and is supported on the top of the oil pot 4. During use, the oil pot 4 is filled with air that accounts for at least one third of the total volume.

[0025] The role of the air here is similar to that of a spring, because the extrusion force generated by the screw cannot be stored in the oil pot 4. If there is no air, the oil in the oil pot 4 will stop flowing out after a part of it is squeezed out. The air will be compressed after the screw squeezes the oil pot 4, thereby storing part of the power, and then the role of the brush 6 is similar to a throttle valve, allowing the lubricating oil to flow out at a slow rate. Of course, the air here can also be replaced by a spring, that is, a spring is set between the screw and the oil pot 4. After the screw is squeezed here, it is necessary to ensure that the brush 6 can always be in a wet state, and no oil spontaneously leaves the brush 6. If it is difficult to control, a throttle orifice plate can be set in the oil pipe 5.

[0026] The mounting bracket 3 includes two bridge-shaped brackets that span the racks and are anchored on the climber 1, and a mounting plate that is parallel to the racks and fixedly connected to the bridge-shaped brackets at both ends. The oil pot 4 is fixed on the mounting plate.

[0027] Here, the ends of the bridge-shaped bracket can be fixed by spot welding.

[0028] The two ends of the oil pot 4 are respectively provided with top covers buckled on the ends. Among the two top covers, the top cover at the upper end is connected as a whole with the screw rod, and the top cover at the lower end is fixed on the mounting plate, and the oil pipe 5 extends into the oil pot 4 from the top cover at the lower end.

[0029] The function of this structure is to cooperate with the extruder 7 to squeeze the oil pot 4. After the top cover at the upper end is connected to the screw rod as a whole, the top cover can be rotated without the need to twist the screw rod by hand.

[0030] A sleeve ring is also sleeved on the middle part of the oil pot 4, which is in clearance fit with the oil pot 4 and is used to prevent the oil pot 4 from being distorted during the extrusion process. The sleeve ring is fixed on the mounting plate.

[0031] The brush 6 is a carbon silicon nylon brush in the shape of a brush head and is detachably inserted into the opening of the oil pipe 5 .

[0032] The carbon silicon nylon brush used here is a very wear-resistant brush 6. In actual use, the bristles of this material are integrated into a bundle similar to a brush head and then inserted into the opening of the oil pipe 5, and then fixed with structural glue. However, even a carbon silicon nylon brush will still be worn out during use, so it is necessary to ensure that it is replaceable.

[0033] The utility model discloses an automatic lubrication system for a climbing frame gear rack, and a method of using the system comprises the following steps:

[0034] Step 1: Pull the oil pot 4 to its longest position, and then fill the oil pot 4 with 2 / 3 of the volume of lubricating oil;

[0035] Step 2: Install the utility model on the climbing frame;

[0036] Step 3: Rotate the top cover on the upper end of the oil pot 4 to squeeze the oil pot 4, ensuring that the brush 6 remains moistened but no lubricating oil drips spontaneously.

[0037] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
