Description

Technical Field

[0001] The invention relates to a lifting construction platform without hanging points. Background Art

[0002] When constructing or repairing equipment on conical columns such as communication base station poles, wind power generation columns, and chimneys, the climbers used to climb the poles cannot be used due to the large diameter of the columns. Maintenance and construction personnel must weld climbing foot pads or U-shaped tubes and other parts on the outer wall of the conical column, starting from the bottom of the conical column, and then stepping on the welded foot pad to weld the next one until they reach the top of the conical column.

[0003] However, this method requires welding dozens or even hundreds of foot pads on the outer wall of the tapered column, which is very troublesome, and it is very dangerous to weld higher foot pads on the elevated foot pads. Even after welding, it is not safe for maintenance and construction personnel to climb several foot pads. Summary of the invention

[0004] In summary, in order to overcome the deficiencies of the prior art, the present invention provides a lifting construction platform without lifting points, which is convenient and safer for maintenance and construction personnel to use.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a lifting construction platform without hanging points, comprising an annular frame and a plurality of climbing devices, the annular frame comprising a main pipe, a secondary pipe detachably connected to the main pipe, and a platform plate for providing a working area for maintenance and construction personnel, the annular frame is provided with a plurality of connecting plates, the climbing device comprises a sliding rod, a sliding sleeve fixedly connected to the connecting plate, and a main telescopic assembly, the sliding sleeve is provided with a sliding groove adapted to the sliding rod, the sliding groove faces the center of the annular frame, the main telescopic assembly controls the sliding rod to reciprocate in the sliding groove, the end of the sliding rod facing the center of the annular frame is provided with a main roller, the main roller is perpendicular to the plane of the annular frame, and the main roller is provided with a driving member for controlling its rotation.

[0006] With such an arrangement, an engineer will measure the angle of the conical column before use, and then adjust the ratio of the rotation speed of the driving part and the telescopic speed of the main telescopic assembly. Then the maintenance and construction personnel can use it by first putting the main pipe on the conical column and then connecting the auxiliary pipe, so that the main roller in the telescopic assembly on the annular frame presses against the outer wall of the conical column. At this time, the diameter of the ring formed by several main rollers is fixed, and the lifting construction platform will fall on the corresponding position of the conical column and will not continue to fall. The maintenance and construction personnel can sit or stand on the platform board to work. When it is necessary to rise, the driving part controls the rotation of the main roller. While the main roller rotates, the main telescopic assembly also controls the telescopic rod to push the sliding rod on the slide It moves in the groove toward the conical column. Since the engineer has set the angle of the conical column in advance, the main roller always presses against the outer wall of the conical column and rolls upward on the outer wall of the conical column. Similarly, when descending, the main roller and the slide bar move in opposite directions. Maintenance and construction personnel weld foot pads on the outer wall of the conical column, and there is no need to climb. They only need to start the switch after setting it up to ascend or descend on the conical column. The number of climbing devices can be set to 3, 4, 5 or more according to the diameter of the conical column. If used on the same conical column, it can be ascended or descended on the conical column without programming during maintenance or construction. The equipment can also be connected to an external portable power source such as a battery, so it can also be used during a power outage.

[0007] Furthermore, the climbing device also includes an auxiliary rod and a secondary telescopic assembly, the auxiliary rod is provided with a secondary roller at one end facing the center of the annular frame, the other end of the auxiliary rod is hinged to the sliding sleeve, and the secondary telescopic assembly controls the auxiliary rod to swing around the hinge point with the sliding sleeve.

[0008] With such arrangement, when the main roller on the sliding rod presses against the conical column, the secondary roller on the auxiliary rod will press against the conical column above the conical column. When the lifting construction platform rises, the secondary telescopic assembly also controls the telescopic rod of the secondary telescopic assembly to lift the middle of the auxiliary rod. Both ends of the secondary telescopic assembly are hinged, and the auxiliary rod will swing on the sliding sleeve, so that the secondary roller always presses against the conical column. The upper and lower rollers and the hinge point of the auxiliary rod form a triangle, which makes the positioning more stable and reduces the possibility of the lifting construction platform tilting to one side.

[0009] Furthermore, a connector that matches the inner diameter of the main pipe is provided at one end of the secondary pipe facing the main pipe, and the connector is connected to the main pipe by bolts after being inserted into the main pipe.

[0010] With such arrangement, the main pipe is firstly put on the tapered column, and then the connector is inserted into the main pipe, and then connected by bolts, so that the auxiliary pipe will no longer rotate around the main pipe, the structure is simple, and the connection is convenient.

[0011] Furthermore, two auxiliary pipes are provided, and a connecting block is provided at one end of the auxiliary pipe opposite to the end provided with the connecting head, and the platform plate includes a fixing plate, and the fixing plate is respectively connected to the connecting blocks on the two auxiliary pipes.

[0012] With this arrangement, the connecting blocks at one end of the two auxiliary pipes are connected to the fixing plate, and the other end is connected to the main pipe. The annular frame will be locked by the fixing plate and will not be opened. The fixing plate can be used to fix the annular frame and provide a working area for maintenance and construction personnel. The structure is simple and the connection is convenient.

[0013] Furthermore, the fixing plate is an L-shaped plate bent away from the center of the annular frame.

[0014] With such arrangement, when maintenance and construction personnel sit on the fixed plate, the L-shaped plate can provide a backrest for the maintenance and construction personnel, thereby providing comfort and reducing the possibility of the personnel slipping off the fixed plate.

[0015] Furthermore, the climbing device also includes a tightening wire and a winding assembly, the tightening wire is connected to each of the sliding rods, and the tightening assembly is used to wind up or release the tightening wire.

[0016] With this setting, the winding speed of the winding assembly is also controlled when the engineer is programming. It is linked when the main roller rolls, and the tightening wire is wound during the rise to reduce the possibility of the main roller being pushed away. The tightening wire is released during the descent, and the tightening wire will be stretched out and will not hinder the descent. The tightening wire and winding assembly can also be set on the auxiliary rod, which is double locked and more stable.

[0017] Furthermore, the tightening assembly is connected to one of the sliding rods in the plurality of climbing devices, and the remaining sliding rods are provided with tightening wheels, and the tightening wheels are provided with rolling grooves adapted to the tightening wires.

[0018] With such arrangement, when the take-up wire is taken up by the take-up mechanism, it will slide in the rolling groove on the take-up wheel on the slide rod. When sliding, the take-up wheel will roll, and the take-up process of the take-up wire will be smoother, reducing the possibility of getting stuck during take-up.

[0019] Furthermore, the platform plate also includes a plurality of pedals, the number of the pedals corresponds to the number of the slide rods, the pedals are connected to the slide rods, the distance from the pedals to the center of the annular frame is greater than the distance from the main roller to the center of the annular frame, and the pedals are always located on the annular frame.

[0020] With such arrangement, maintenance and construction personnel can stand on the pedal in addition to the fixed plate to repair or construct the entire outer wall of the tapered tube, and the pedal will move with the slide bar, always keeping a certain distance from the tapered column and will not get stuck to the tapered column. Moreover, since the distance from the pedal to the center of the annular frame is greater than the distance from the main roller to the center of the annular frame, the pedal will not affect the operation of the main roller. The pedal can also be provided with clearance grooves at the positions of the auxiliary rod and the secondary telescopic assembly, so that it will not get stuck during movement and has more room for movement.

[0021] Furthermore, a plurality of pedals are arranged to overlap with each other around the edge of the annular frame.

[0022] With this arrangement, the edges of the pedals overlap each other, and when the pedals move with the slide bar, the overlapping area will change accordingly. The two pedals will not separate to create a gap during the movement, which provides greater safety.

[0023] Furthermore, a safety railing is provided on the side of the pedal facing away from the center of the annular frame.

[0024] With this arrangement, maintenance and construction personnel will be protected by safety railings to avoid falling when performing maintenance or construction on the pedals, which is safer. BRIEF DESCRIPTION OF THE DRAWINGS
