Description

Technical Field

[0001] The invention relates to the technical field of a pole holding system, in particular to a lifting wire rope supporting pulley assembly and a pole holding system for pole tower assembly. Background Art

[0002] When assembling towers with systems such as double-arm floor-standing booms, a traction system including winches and other equipment will be set up on the ground; the traction wire rope at the traction system is pulled from the traction yard where the traction system is located to the boom through a pulley system to realize functions such as lifting the boom and lift tower components for construction.

[0003] However, the current pulley system is deployed at the pole or tower, and the traction system directly leads to the bottom of the pole. However, there is a long distance between the traction system and the pole, and the wire rope is basically in an unsupported state during this distance, and may be suspended in the air or in contact with ground objects, which will cause the wire rope in this section to easily interfere with the ground, and its unstable state will affect the safe progress of construction. Summary of the invention

[0004] The invention provides a lifting wire rope supporting pulley assembly and a pole holding system for pole tower assembly, which can overcome certain defects of the prior art.

[0005] The lifting wire rope supporting pulley assembly according to the present invention comprises a body; the body comprises a supporting member for supporting the wire rope, and a supporting member for supporting the supporting member on the ground; The supporting member comprises a supporting plate connected to the supporting member, and a pulley for supporting the steel wire rope is rotatably matched at one side of the supporting plate.

[0006] Through the support member and the bearing member of the present invention, the pulley of the bearing member can be supported on the ground, and multiple groups of bodies can be arranged at intervals between the holding rod and the traction system, and the steel wire rope between the holding rod and the traction system can be supported at intervals to prevent the steel wire rope from interfering with the ground, thereby ensuring the construction safety when assembling the pole tower.

[0008] In the present invention, by setting the limiting assembly, the opening between the two support plates and the pulley can be blocked by the limiting block. Since the wire rope has a certain offset when the boom is running, the limiting assembly can prevent the wire rope from detaching from the main body due to the offset, thereby ensuring the stability of the wire rope during operation.

[0009] Preferably, the locking member includes a sliding cavity provided at the end of the limit block away from the pulley, and two sliders are slidably fitted in the sliding cavity; a clamping block extending to the outside of the limit block is provided at the opposite ends of the two sliders; a clamping hole for the clamping block to extend into is provided at the two support plates; a first spring is also provided inside the sliding cavity and pressed between the two sliders, and the first spring is used to enable the clamping block to maintain the tendency to move toward the clamping hole; a cover plate for blocking the sliding cavity is provided at the limit block; a slot passing through the sliding cavity is provided at the cover plate; and a paddle extending out of the slot is provided at the slider.

[0010] In the present invention, by setting the paddle, the slider, the first spring and the clamping block, the two clamping blocks can be driven to move when the two paddles are pinched, so that the two clamping blocks can be matched with or separated from the clamping holes of the two support plates, so that the limit block and the supporting member can be quickly assembled, and in actual construction, the main body is provided with multiple groups, and the assembly time can be greatly reduced through the above-mentioned rapid assembly.

[0011] Preferably, a bottom plate perpendicular to the support plate is provided on both sides of the limit block; a positioning rod is provided on one end face of the bottom plate away from the cover plate; and a positioning cylinder for the positioning rod to extend into is provided on the opposite sides of the two support plates.

[0012] In the present invention, by setting the positioning rod and the positioning cylinder, the clamping block can keep the limit assembly stable after the clamping hole is matched, and the positioning rod can be pre-plugged and matched with the positioning cylinder. After matching, the clamping block and the clamping hole can automatically maintain a straight line, thereby reducing assembly time.

[0013] Preferably, an anti-damage part is provided at the limit block; the anti-damage part includes a notch arranged along the length direction of the wire rope; the notch passes through both sides of the limit block and one end face of the limit block close to the wire rope, and is connected with the sliding cavity; a mounting frame located between two sliding blocks is provided inside the sliding cavity; a limit roller is provided at the mounting frame, which is slidably matched with the mounting frame along the height of the limit block and can rotate, and the axial direction of the limit roller is kept perpendicular to the axial direction of the positioning rod; one end of the limit block is rotatably matched with limit rollers located on both sides of the notch, and the axial direction of the limit roller is kept parallel to the axial direction of the positioning rod; the limit roller, the limit roller and the pulley constitute a section for accommodating the wire rope.

[0014] In the present invention, by setting the anti-damage parts, the limit roller and the two limit rollers at the notch can form a U-shaped area, so that the wire rope will not rub against the right-angle edge of the limit block after being offset, causing wear, and the limit roller and the two limit rollers can achieve rolling friction with the wire rope when the wire rope is retracted and released, thereby further limiting the position while reducing the wear of the wire rope.

[0015] Preferably, a threaded barrel that penetrates the notch is provided at one end face of the mounting frame away from the limiting roller; the threaded barrel is threadedly matched with a push rod; the push rod is arranged along the radial direction of the limiting roller; one end of the push rod extends out of the slot, and the other end is semicircular and can be tightly pressed against the limiting roller.

[0016] In the present invention, by setting the abutment rod, the abutment rod can be pressed against the surface of the limiting roller after rotation, so that the limiting roller cannot move upward. Because the wire rope has an offset during operation, the maximum height of the limiting roller can be limited by rotating the screw rod to adjust the height of the screw rod, that is, the amount of upward offset of the wire rope is limited, so that the wire rope can operate safely within the set offset range.

[0017] Preferably, a protective component is provided at the cover plate; the protective component includes a plurality of vertical poles arranged at the end surface of the cover plate, and a sealing cover for sealing the slot; a ring slidingly matched with the vertical pole is provided on the outer side of the sealing cover; a limit plate is provided at the end of the vertical pole, and a second spring is pressed between the limit plate and the ring; the second spring is used to enable the sealing cover to maintain a state of sealing the slot.

[0018] In the present invention, by setting up the protection component, the sealing cover can seal the notch to prevent rainwater from entering the threads of the threaded barrel and the push rod, and to protect the first spring and other positions that may be affected by rust and performance. In addition, the sealing cover can always be tightly pressed against the cover plate due to the second spring to seal the notch, thereby achieving a better protection effect.

[0019] Preferably, an oil storage box is provided at one end surface of the sealing cover away from the cover plate, and a cavity is provided at the oil storage box, in which a sleeve penetrating into the sealing cover is provided; one end of the sleeve located inside the oil storage box is in a closed state, and is provided with a through oil seepage hole; one end of the sleeve located inside the sealing cover is in an open state, and is sleeved with the end of the push rod, and a sponge block is provided in the sleeve and is tightly pressed against the end of the push rod; a sealing cover for sealing the cavity is provided at the oil storage box.

[0020] In the present invention, through the arrangement of the oil storage box, the sleeve and the sponge block, the protective component can also have the characteristic of easy lubrication. During daily maintenance, it is only necessary to pour the lubricating oil into the oil storage box, and the lubricating oil will enter the interior of the sleeve from the oil seepage hole of the sleeve, and be absorbed by the sponge block when passing through the sponge block. Since the sponge block is tightly pressed against the end of the push rod, the lubricating oil will seep onto the surface of the push rod, and flow to the push rod, the threaded barrel, the mounting frame, the limit roller, the wire rope and the pulley in sequence; thereby, the threads of the push rod and the threaded barrel, the contact portion between the push rod and the surface of the limit roller, the contact portion between the limit roller and the wire rope, and the contact portion between the wire rope and the pulley can all be lubricated, thereby achieving the effect of pouring oil in one step and slowly penetrating and lubricating everywhere, and lubricating each friction part to prolong the service life.

[0021] Preferably, the support member includes a fixing seat and a mounting seat, both of which are rectangular; one end of the mounting seat is fixed to two support plates; the fixing seat is provided with a slot arranged along the length direction of the fixing seat; the slot is used for the mounting seat to extend into; the mounting seat and the fixing seat are both provided with a number of positioning holes for assembling fasteners; the mounting seat is provided with a fixing plate; the fixing seat is provided with a back plate parallel to the fixing plate; the fixing plate is threaded with a bolt whose end is tightly pressed against the back plate.

[0022] In the present invention, by setting the adjusting member, the length of the mounting seat extending into the fixing seat can be adjusted by rotating the bolt, so that the positioning hole to be assembled with the fastener can be aligned, and there is no need to hold the supporting member and the mounting seat with one hand and operate the fastener with the other hand to fix the mounting seat and the fixing seat during assembly, thereby reducing the difficulty of single-person assembly.
