Description

Technical Field

[0001] The utility model belongs to the technical field of continuous beam construction, and more specifically relates to a continuous beam hanging basket construction lifting device. Background Art

[0002] Continuous beam construction using a large hanging basket is a common bridge construction method. During construction, the piers are constructed first, and then the hanging baskets are installed symmetrically on both sides of the piers. The movement of the hanging baskets allows the concrete of the continuous beam to be poured segment by segment, gradually extending the beam. Due to the diverse sizes and specifications of the building materials involved in continuous beam construction, cranes are often equipped with adjustable crossbeam spreaders to accommodate the lifting and transportation needs of different sizes.

[0003] Existing adjustable crossbeam slings include a crossbeam and a lifting ring mounted on the crossbeam. Multiple protrusions are fixed to the upper surface of the crossbeam along its length. The lifting rings rely on their own weight to clamp between two adjacent protrusions, leaving a gap between the lifting rings and the crossbeam in the vertical direction. To adjust the position of the lifting rings, the rings are lifted and then placed between two adjacent protrusions at different locations, thereby adjusting the position of the lifting rings. Although this connection method is very convenient for adjusting the position of the lifting rings, the connection between the lifting rings and the crossbeam is not secure. If the crossbeam accidentally overturns, the lifting rings are likely to fall out from between two adjacent protrusions, causing the lifting rings to tilt and change position, posing certain safety risks during use. Utility Model Content

[0004] The utility model aims to provide a continuous beam hanging basket construction lifting device, aiming to improve the firmness of the connection between the beam and the lifting ring.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a continuous beam hanging basket construction lifting device, comprising:

[0006] beam;

[0007] Two lifting rings are respectively slidably mounted on the crossbeam, and the inner peripheral walls thereof abut against the outer peripheral wall of the crossbeam;

[0008] Among them, a plurality of slots are evenly distributed on the beam along the length direction; each of the hanging rings is connected to an elastic locking piece, which has elastic freedom to move toward the beam, and the elastic locking piece is suitable for being inserted into any of the slots.

[0009] In a possible implementation, a handle is fixedly provided on the hanging ring;

[0010] The position of the handle corresponds to the position of the elastic locking member, an action member is slidably provided on the handle, and the action member and the elastic locking member are connected by a connecting rod;

[0011] When the handle is held, the actuating member retracts into the handle and the elastic locking member disengages from the slot;

[0012] When the handle is released, the actuating member extends from the handle and the elastic locking member is inserted into the slot.

[0013] In a possible implementation, the elastic locking member includes:

[0014] a locking member, vertically slidably disposed on the lifting ring and fixed to the connecting rod;

[0015] An elastic member is provided between the locking member and the lifting ring and is sleeved on the connecting rod, and is used for pushing the locking member to move toward the direction close to the crossbeam.

[0016] In one possible implementation, the handle includes:

[0017] A connecting portion, fixedly arranged on the lifting ring;

[0018] A gripping portion, fixedly disposed on the connecting portion;

[0019] Wherein, the action piece is slidably arranged on the holding portion and extends from the outer wall of the holding portion.

[0020] In a possible implementation, a support plate protruding along the length direction of the beam is fixedly provided on the hanging ring, and the support plate is attached to the surface of the beam.

[0021] In a possible implementation, baffles for blocking the lifting rings are fixedly provided at both ends of the crossbeam.

[0022] In a possible implementation, a leg for supporting the crossbeam is hingedly connected to the baffle, and the leg is fixed to the crossbeam via a fastener;

[0023] The supporting legs can be rotated to a supporting state located below the cross beam and rotated to a storage state in contact with the baffle.

[0024] In a possible implementation, the fastener is a connecting bolt threadedly connected to the crossbeam, and a connecting rope is connected between the head of the connecting bolt and the crossbeam to prevent the connecting bolt from being lost.

[0025] In one possible implementation, a first positioning plate is fixedly provided on the support leg. When the support leg is rotated until the first positioning plate abuts against the lower surface of the beam, the screw portion of the connecting bolt passes through the first positioning plate and is threadedly connected to the beam, and the head of the connecting bolt abuts against the first positioning plate to put the support leg in the supporting state.

[0026] In one possible implementation, a second positioning plate is fixedly provided on the support leg. When the support leg is rotated until the second positioning plate abuts against the upper surface of the beam, the screw portion of the connecting bolt passes through the second positioning plate and is threadedly connected to the beam, and the head of the connecting bolt abuts against the second positioning plate to place the support leg in the retracted state.

[0027] The utility model provides a continuous beam hanging basket construction lifting device. Compared with the existing technology, the beneficial effect is that the inner peripheral wall of the lifting ring and the outer peripheral wall of the beam are abutted together, so that the lifting ring fits tightly on the beam, ensuring the stability of the lifting ring's position in the vertical direction of the beam, and avoiding the problem of shaking caused by the upper and lower gaps between the lifting ring and the beam in the existing lifting equipment. At the same time, by inserting the elastic locking member into the slot on the beam, the lifting ring is stabilized in the horizontal direction of the beam, effectively preventing the lifting ring from moving up and down or left and right relative to the beam during use, greatly improving the connection firmness of the entire lifting device and reducing the safety hazards caused by unstable connection.

DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] See Figure 1 and Figure 2 , a continuous beam hanging basket construction lifting device provided by the utility model is now described. A continuous beam hanging basket construction lifting device comprises a crossbeam 1 and two lifting rings 2. The two lifting rings 2 are respectively slidably mounted on the crossbeam 1, and the inner peripheral walls of the lifting rings 2 are against the outer peripheral walls of the crossbeam 1. A plurality of slots 11 are evenly distributed along the length direction on the crossbeam 1. Each lifting ring 2 is connected to an elastic locking member, which has elastic freedom to move toward the crossbeam 1, and the elastic locking member is suitable for being inserted into any slot 11.

[0037] The inner walls of the two lifting rings 2 are against the outer walls of the beam 1, making the connection between the lifting rings 2 and the beam 1 tighter, so that the lifting rings 2 can maintain a relatively stable position relationship with the beam 1, reducing the possibility of the lifting rings 2 shaking on the beam 1.

[0038] By adjusting the positions of the two lifting rings 2 on the beam 1, the lifting rings 2 can be flexibly adjusted according to the actual lifting and transportation requirements. When the position of the lifting ring 2 needs to be adjusted, it is only necessary to overcome the elastic force of the elastic locking member, pull it out of the currently inserted slot 11, and then slide the lifting ring 2 along the length of the beam 1 to the desired position. Then, release the elastic locking member, and the elastic locking member will automatically insert into the slot 11 corresponding to the new position, thereby fixing the position of the lifting ring 2. This meets the lifting and transportation requirements of building materials of different sizes and ensures a stable connection between the lifting ring 2 and the beam 1 after adjustment.

[0039] In some embodiments, see Figure 3A handle 3 is fixed to the lifting ring 2. The position of the handle 3 corresponds to the position of the elastic locking member. An actuating member 41 is slidably mounted on the handle 3. The actuating member 41 and the elastic locking member are connected by a connecting rod 42. When the handle 3 is grasped, the actuating member 41 retracts into the handle 3, and the elastic locking member disengages from the slot 11. When the handle 3 is released, the actuating member 41 extends from the handle 3, and the elastic locking member is inserted into the slot 11.

[0040] When the position of the lifting ring 2 needs to be adjusted, the construction worker only needs to hold the handle 3. At this time, the actuating member 41 will retract into the handle 3. Through the transmission of the connecting rod 42, the elastic locking member will disengage from the slot 11, so that the lifting ring 2 can be slid to the appropriate position along the beam 1. When the position of the lifting ring 2 is adjusted, the handle 3 is released, the actuating member 41 will extend from the handle 3, and the elastic locking member will then be inserted into the slot 11 under its own elastic action, thus fixing the position of the lifting ring 2.

[0041] The locking and unlocking of the lifting ring 2 is controlled by holding and releasing the handle 3. The operation is simple and intuitive, and does not require complicated tools or additional operating steps. This greatly improves the efficiency of adjusting the position of the lifting ring 2 and facilitates construction personnel to quickly complete the adjustment of the lifting device according to actual conditions.

[0042] In some embodiments, see Figure 3 The elastic locking member includes a locking member 51 and an elastic member 52. The locking member 51 is vertically slidably mounted on the lifting ring 2 and fixed to the connecting rod 42. The elastic member 52 is disposed between the locking member 51 and the lifting ring 2 and sleeved on the connecting rod 42 to push the locking member 51 toward the beam 1.

[0043] Exemplarily, the elastic member 52 is a spring, one end of the spring is fixedly connected to the locking member 51, and the other end of the spring is fixedly connected to the hanging ring 2. The spring is always in a compressed state, which enables the spring to exert a stable elastic force on the locking member 51, pushing the locking member 51 to move toward the direction close to the beam 1.

[0044] When the handle 3 is released, the elastic member 52 pushes the locking member 51 downward, causing it to engage with the slot 11 of the beam 1, thereby firmly locking the lifting ring 2 to the beam 1 in the horizontal direction. This automatic pushing action of the elastic member 52 ensures that the lifting ring 2 remains firmly connected to the beam 1 without human intervention to adjust its position, thus ensuring the safety of the lifting operation.

[0045] When the position of the lifting ring 2 needs to be adjusted and the handle 3 is held, the force transmitted through the connecting rod 42 overcomes the thrust of the elastic member 52, causing the locking member 51 to slide upward and disengage from the slot 11, thereby allowing the position of the lifting ring 2 to be adjusted.

[0046] In some embodiments, see Figure 3 The handle 3 includes a connecting portion 31 and a gripping portion 32. The connecting portion 31 is fixedly mounted on the hanging ring 2. The gripping portion 32 is fixedly mounted on the connecting portion 31. The actuating member 41 is slidably mounted on the gripping portion 32 and extends from the outer wall of the gripping portion 32.

[0047] When a construction worker grips the handle 3, his hand naturally grips the grip portion 32. At this point, he can easily operate the actuating member 41 with his fingers, causing it to retract into the grip portion 32. The connecting rod 42 then unlocks the elastic locking member, thereby enabling sliding adjustment of the lifting ring 2. After adjusting the position of the lifting ring 2, the construction worker naturally releases the grip portion 32, and the actuating member 41 naturally extends from the grip portion 32 under the action of the elastic member 52, facilitating the next adjustment.

[0048] In some embodiments, see Figure 4 A support plate 21 protruding along the length direction of the beam 1 is fixed on the lifting ring 2, and the support plate 21 is attached to the surface of the beam 1. During the lifting process, the support plate 21 plays an auxiliary supporting role, further enhancing the connection stability of the lifting ring 2 and the beam 1.

[0049] When lifting a heavy object, the weight of the object is transferred to the crossbeam 1 through the lifting ring 2. At this time, the contact surface between the support plate 21 and the crossbeam 1 can share some of the pressure, preventing the lifting ring 2 from deforming due to excessive pressure. At the same time, the support plate 21 protrudes along the length of the crossbeam 1 to limit the lifting ring 2 to a certain extent, keeping the lifting ring 2 stable on the crossbeam 1 and preventing the lifting ring 2 from tilting.

[0050] In some embodiments, see Figure 4 and Figure 5 At both ends of the beam 1, baffles 12 are fixedly provided to block the lifting rings 2. The baffles 12 play a role in limiting, ensuring that the lifting rings 2 always move within a suitable range on the beam 1, and preventing the lifting rings 2 from sliding off the ends of the beam 1 due to sliding adjustment or unexpected circumstances.

[0051] In some embodiments, see Figure 4 and Figure 5 The baffle 12 is hinged with a leg 13 for supporting the beam 1, and the leg 13 is fixed to the beam 1 by a fastener. The leg 13 has a support state of rotating to be located below the beam 1 and a storage state of rotating to be in contact with the baffle 12.

[0052] When the position of the lifting ring 2 needs to be adjusted, the legs 13 are rotated to the supporting state. The legs 13 can effectively support the beam 1 so that the lifting ring 2 does not come into contact with the ground, thereby facilitating the sliding of the lifting ring 2 on the beam 1. During lifting operations, the legs 13 are rotated to the retracted state so that the legs 13 do not hinder the lifted building materials.

[0053] In some embodiments, see Figure 4 and Figure 5 The fastener is a connecting bolt 14 threadedly connected to the crossbeam 1, and a connecting rope 15 is connected between the head of the connecting bolt 14 and the crossbeam 1 to prevent the connecting bolt 14 from being lost.

[0054] During use of the lifting device, the connecting bolts 14 are used to fix the relative positions of the legs 13 and the beam 1, ensuring that the legs 13 can be firmly connected to the beam 1 in both the supporting state and the retracted state.

[0055] When it is necessary to remove the connecting bolt 14 to switch the status of the support leg 13, the connecting bolt 14 will not be easily lost due to the connection of the connecting rope 15, which is convenient for construction workers to reinstall and use it later, ensuring the normal use of the lifting device and reducing the inconvenience and potential safety hazards caused by loss.

[0056] In some embodiments, see Figure 4 and Figure 5 A first positioning plate 131 is fixedly provided at one end of the support leg 13 close to the hinge axis. When the support leg 13 rotates until the first positioning plate 131 rests on the lower surface of the beam 1, the screw portion of the connecting bolt 14 passes through the first positioning plate 131 and is threadedly connected to the beam 1, and the head of the connecting bolt 14 rests on the first positioning plate 131, so that the support leg 13 is in a supporting state.

[0057] The first positioning plate 131 plays a role in positioning the legs 13, so that the legs 13 can be easily adjusted to a supporting state, reducing the difficulty of operation. At the same time, the first positioning plate 131 rests on the lower surface of the beam 1, also playing a better supporting effect on the beam 1.

[0058] In some embodiments, see Figure 4 and Figure 5 A second positioning plate 132 is fixedly provided at one end of the support leg 13 away from the hinge axis. When the support leg 13 rotates until the second positioning plate 132 abuts against the upper surface of the beam 1, the screw portion of the connecting bolt 14 passes through the second positioning plate 132 and is threadedly connected to the beam 1, and the head of the connecting bolt 14 abuts against the second positioning plate 132, so that the support leg 13 is in a retracted state.

[0059] The second positioning plate 132 positions the legs 13, allowing them to be easily adjusted to the stowed position, reducing the difficulty of operation. At the same time, when the legs 13 are rotated to the supporting position, the second positioning plate 132 is at the bottom of the legs 13, so that when the beam 1 is placed on the ground, the second positioning plate 132 can contact the ground, increasing the contact area with the ground and making the beam 1 more stable when placed on the ground.

[0060] In summary, the present invention provides a continuous beam hanging basket construction lifting device. Compared with the prior art, the inner peripheral wall of the lifting ring 2 abuts against the outer peripheral wall of the crossbeam 1, allowing the lifting ring 2 to fit tightly against the crossbeam 1, ensuring the stability of the lifting ring 2 in the vertical direction of the crossbeam 1. At the same time, the elastic locking member is inserted into the slot 11 on the crossbeam 1, thereby achieving the stability of the lifting ring 2 in the horizontal direction of the crossbeam 1, effectively preventing the lifting ring 2 from moving up and down or left and right relative to the crossbeam 1 during use, greatly improving the connection security of the entire lifting device and reducing the safety hazards caused by unstable connection.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
