Technical Field

[0001] This utility model relates to the field of jack hanger technology, specifically to a pulley-type jack hanger. Background Technology

[0002] Jacks are an important construction tool, mainly used for lifting and supporting heavy objects. They are widely used in building construction, bridge construction and other fields. In building construction, when precast segmental beams are tensioned, tensioning jacks are used at the end faces of the segmental beams. In practice, they have the advantages of simple operation, stable structure and good performance.

[0003] The prior art discloses a tension jack position adjustment bracket with application number CN202020365569.9.

Two sets of second mounting shafts are passed through the sides of each of the two sets of second concave slide blocks via bearings. Second rollers are fitted onto the sidewalls of the four sets of second mounting shafts on the same side. Each of the two concave sliding blocks is equipped with a lifting ring at its lower part. A hand-operated hoist runs through the interior of each of the two sets of lifting rings. A tension jack is installed at one end of each of the two sets of hand-operated hoists. Mounting boxes are installed on both sides of the hanging frame. A protective cover is installed inside the hanging frame. Two sets of connecting hoses run through the end face of the protective cover. A telescopic hose is installed at one end of each of the two sets of connecting hoses. A protective glove is installed at one end of each of the two sets of telescopic hoses. Mounting perforated plates are installed on both sides of the interior of the protective cover. T-shaped rods slide through the interior of each of the two sets of mounting perforated plates. Annular brake pads are installed at the lower ends of each of the two sets of T-shaped rods. Telescopic springs are sleeved on the side walls of each of the two sets of T-shaped rods.

[0010] Furthermore, both sets of mounting boxes have lead levers installed inside via bearings, and lead screw sleeves are fitted onto the side walls of both sets of lead screw sleeves. Connecting plates are fixedly fitted onto the side walls of both sets of lead screw sleeves. Vertical rods slide through the upper parts of both sets of connecting plates, with their ends fixedly connected to the top and bottom surfaces of the two sets of mounting boxes, respectively. Two sets of connecting rods are installed at the lower parts of both sets of connecting plates, with the lower ends of the two sets of connecting rods on the same side sliding through one set of mounting boxes on the same side. On the inner bottom surface of the bracket, brake plates are installed at the lower ends of the two sets of connecting rods on the same side. A counterweight box is installed on the upper part of the bracket body, and a forward and reverse motor is installed on the upper part of the counterweight box. A main gear is fixedly sleeved at the output end of the forward and reverse motor. Two sets of transmission shafts are passed through the inner bottom surface of the counterweight box via bearings. Driven gears are fixedly sleeved on the side walls of the two sets of transmission shafts. The two sets of transmission shafts are connected to the two sets of lead levers respectively through couplings. An electrical control box is installed on one side of the inner side of the bracket body.

[0011] Furthermore, the electrical control box contains a control panel and a battery, and the control panel is electrically connected to the battery and the forward and reverse motor via wires.

[0012] Furthermore, the two sets of lead levers and the two sets of lead screw threads cooperate with each other.

[0013] Furthermore, the main gear meshes with the two sets of driven gears.

[0014] Furthermore, the lower part of the hanger frame is equipped with four sets of first self-locking casters.

[0015] Furthermore, a second self-locking caster wheel is installed at the lower part of the protective cover.

[0016] Furthermore, both the front and rear ends of the protective cover are permeated with breathable filters, and a door is installed on the rear end of the protective cover via a hinge.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a pulley-type jack hanger, which has the following advantages:

[0019] (1) This utility model adopts a protective cover. When actually using the pulley-type jack, the operator first opens and closes the box door, then enters the inside of the protective cover, and then resets the box door. The operator then inserts his / her hands into the inside of the two sets of protective gloves through the two sets of connecting hoses and the two sets of telescopic hoses. At this time, the operator can stand on the annular brake pad, which can move down to contact the ground. During this process, the two sets of T-shaped rods that move down and the two sets of fixed mounting holes can compress the two sets of telescopic springs. At this time, the protective cover is fixed in position. The operator's hands can move the two sets of second I-beams and the two sets of second concave slides through the two sets of protective gloves. When the two sets of first I-beams are in position, the operator can move the two sets of second I-beams and the two sets of second concave slides. When the two concave sliding blocks are moved to the appropriate position, the operating height of the two sets of tension jacks can be adjusted by the two sets of hand-operated hoists. After use, the operator's feet are removed from the annular brake pads. The two sets of telescopic springs, under their own elastic force, can push the two sets of T-shaped rods to move the annular brake pads upwards and off the ground. At this time, the operator can move the protective cover with the help of the four sets of second self-locking universal wheels. The operator is inside the protective cover, and moving external objects cannot directly contact the operator, thus protecting the operator. The protective cover has a protective structure that can ensure the safety of the operator during operation and provide a guarantee for the safe use of the pulley-type jack hanger.

[0020] (2) This utility model adopts an installation box. Before actually using the pulley-type jack hanger, the hanger frame can be moved to the usage position with the help of four sets of first self-locking universal wheels. Then, the control panel is used to make the forward and reverse motor work. The output end of the forward and reverse motor can drive the main gear to rotate. Since the main gear meshes with the two sets of driven gears, the rotating main gear can drive the two sets of driven gears to rotate. The two sets of driven gears can drive the two sets of lead levers to rotate through the two sets of transmission shafts. Since the two sets of lead levers and the two sets of lead screws are threaded together, the two sets of driven gears can rotate. The lever assembly can push two sets of lead screw sleeves downwards. The downward-moving lead screw sleeves can cause two sets of brake plates to move downwards via two sets of connecting plates and four sets of connecting rods. When the two sets of brake plates are in contact with the ground, the stability of the hanger frame can be ensured. Using the control panel, the output end of the forward and reverse motor can be rotated in the opposite direction, which can cause the two sets of brake plates to move upwards and reset, ready for the next use. The two sets of vertical rods can ensure the stability of the two sets of connecting plates moving up and down. The installation box can ensure the stability of the bracket during use, improving the practicality of the pulley-type jack hanger. Attached Figure Description

Two sets of connecting rods 28 are mounted on the lower parts of both sets of connecting plates 26. The lower ends of the two sets of connecting rods 28 on the same side slide through the bottom surface of the interior of the same set of mounting boxes 14. Brakes are installed at the lower ends of the two sets of connecting rods 28 on the same side. Plate 29, a counterweight box 30 is installed on the upper part of the hanger frame 1, and a forward and reverse motor 31 is installed on the upper part of the counterweight box 30. The output end of the forward and reverse motor 31 is fixedly sleeved with a main gear 32.

An electrical control box is installed on one side of the interior of the hanger frame 1. The installation box 14 can ensure the stability of the support during use and improve the practicality of the pulley jack hanger.

[0035] In one embodiment, the control box contains a control panel and a battery. The control panel is electrically connected to the battery and the forward / reverse motor 31 via wires. The control circuit of the control panel can be implemented by simple programming by those skilled in the art and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0036] In one embodiment, the two sets of lead levers 24 and the two sets of lead screw sleeves 25 are threaded together to facilitate adjustment of the usage position of the two sets of lead screw sleeves 25.

[0037] In one embodiment, the main gear 32 meshes with two sets of driven gears 34 to ensure that the main gear 32 can drive the two sets of driven gears 34 to rotate.

[0038] In one embodiment, four sets of first self-locking casters are installed on the lower part of the hanger frame 1.

[0039] In one embodiment, a second self-locking caster wheel is installed on the lower part of the protective cover 2.

[0040] In one embodiment, both the front and rear ends of the protective cover 2 are permeated with a breathable filter 15, and the rear end of the protective cover 2 is fitted with a door 19 via a hinge.

[0041] Working principle:

[0042] In actual use of the pulley-type jack hoist, the operator first opens and closes the box door 19, then enters the interior of the protective cover 2, and then resets the box door 19. The operator then inserts their hands through two sets of connecting hoses 16 and two sets of telescopic hoses 17 into the interior of two sets of protective gloves 18. At this time, the operator can stand on the annular brake pad 22, which can move down to contact the ground. During this process, the two sets of T-shaped rods 21 that move down and the two sets of fixed mounting holes 20 can compress the two sets of telescopic springs 23. At this time, the protective cover 2 is fixed in position, and the operator's hands can move the two sets of second I-beams 7 and the two sets of second concave slides 8 through the two sets of protective gloves 18. When the two sets of second concave slides 8 are moved to the appropriate position, the operating height of the two sets of tension jacks 13 can be adjusted by the two sets of hand-operated hoists 12. After use, the operator's feet are removed from the annular brake pad 22, and the two sets of telescopic springs 23, under their own elastic force, can push the two sets of T-shaped rods 21 to move the annular brake pad 22 upwards and off the ground. At this time, the operator can move the protective cover 2 with the help of the four sets of second self-locking universal wheels. The operator is located inside the protective cover 2, and moving external objects cannot directly contact the operator, thus protecting the operator. The protective cover 2 has a protective structure that can ensure the operator's safety. Safety during operation is ensured, guaranteeing the safe use of the pulley-type jack. Before actual use, the jack frame 1 can be moved to the operating position using four sets of first self-locking casters. Then, the control panel is used to activate the forward / reverse motor 31. The output of the motor 31 drives the main gear 32 to rotate. Since the main gear 32 meshes with two sets of driven gears 34, the rotating main gear 32 pushes the two sets of driven gears 34 to rotate. The rotating driven gears 34 can then rotate two sets of lead levers 24 via two sets of transmission shafts 33. Because the two sets of lead levers 24 and the two sets of lead screw sleeves 25 are threaded together... In conjunction with the rotating two sets of lead levers 24, the two sets of lead screw sleeves 25 can be pushed down. The two sets of lead screw sleeves 25, which are moved down, can cause the two sets of brake plates 29 to move down through the two sets of connecting plates 26 and the four sets of connecting rods 28. When the two sets of brake plates 29 are in contact with the ground, the stability of the hanger frame 1 can be ensured. Using the control panel, the output end of the forward and reverse motor 31 can be rotated in the opposite direction. At this time, the two sets of brake plates 29 can be moved up and reset, ready for the next use. The two sets of vertical rods 27 can ensure the stability of the two sets of connecting plates 26 moving up and down. The installation box 14 can ensure the stability of the bracket during use, and improve the practicality of the pulley jack hanger.
