Abstract
Description
Technical Field
[0001] This application relates to the technical field of pipeline construction, and in particular to a pipeline hoisting device for municipal construction. Background Technology
[0002] Municipal pipeline networks are typically constructed by splicing together several pipe segments (concrete pipes, steel pipes, etc.).
[0003] Due to pipeline specifications, some pipeline segments can weigh tens or even hundreds of kilograms. Currently, the transportation of such pipeline segments mainly relies on large cranes such as truck cranes and crawler cranes. During construction, the pipeline segments are tied into place with cables and other means, and then the large cranes lift them to the designated location.
[0004] Large crane construction usually requires open space, but in some construction sites, such as old city streets, large cranes are often difficult to access due to objective site conditions (dense buildings, narrow streets, etc.).
[0005] When large cranes cannot be brought in to work on site, the transportation of pipe sections often has to rely on auxiliary tools such as flatbed trucks and crowbars. This is not only inefficient, but also usually lacks effective restraint on the pipe sections, which can cause them to roll off during transportation, resulting in collision damage, safety risks, and serious impact on the construction progress. Utility Model Content
[0006] To facilitate the handling of pipe segments in construction areas with limited space, this application provides a pipe hoisting device for municipal construction.
[0007] This application provides a pipeline hoisting device for municipal construction, which adopts the following technical solution: A pipeline hoisting device for municipal construction includes several hoisting units; The hoisting unit includes a hoisting beam, with supports vertically connected to both ends of the hoisting beam. Each support includes a longitudinal support rod and a transverse support rod. The top end of the longitudinal support rod is connected to the hoisting beam, and the transverse support rod is vertically connected to the bottom end of the longitudinal support rod. Several casters are installed at the bottom end of the transverse support rod. Each of the lifting beams is equipped with a hand chain hoist, and each hand chain hoist hook is attached to a rope loop, which is used to connect pipe sections. The lifting beams of adjacent lifting units are connected by connecting rods.
[0008] By adopting the above technical solution, after the rope loop is fitted onto the preset lifting point of the pipe segment, the rope loop is pulled upward by the hand-operated hoist on the lifting beam to lift the pipe segment off the ground. Then, the lifting unit is pushed, and the universal wheels at the bottom of the lifting unit drive the lifting frame and the lifted pipe segment to the designated position. Compared with the traditional operation method of transporting pipe segments by flatbed truck or by pry bar in a restricted area, the pipe segment is lifted and transported smoothly through two lifting frame units, which effectively reduces the difficulty of transporting pipe segments and improves the efficiency of transporting pipe segments. At the same time, the rope loop is used to limit the circumferential movement of the pipe segment, which is conducive to more stable transport of the pipe segment. The connecting rod is used to connect and limit the adjacent lifting units, which helps to improve the connection and integration of adjacent lifting units, and thus facilitates more stable lifting of pipe segments.
[0009] Preferably, each of the hand-operated hoists is connected to a sliding member at its top, and the sliding member is slidably connected to the corresponding lifting beam.
[0010] By adopting the above technical solution, before the pipe segment is hoisted to the designated position by the hand chain hoist, the rope loop and the pipe segment can be moved horizontally along the length of the hoisting beam by sliding the hand chain hoist, thereby adjusting the horizontal position of the pipe segment and making it easier to hoist the pipe segment to the designated position.
[0011] Preferably, the lifting beam is an I-beam; The sliding component includes two support plates; the two support plates are located on opposite sides of the suspension beam, and each of the two support plates is rotatably connected to a traveling wheel on its opposite side. The traveling wheels on the opposite side of the two support plates are respectively attached to the opposite sides of the lower flange of the suspension beam.
[0012] By adopting the above technical solution, and by having the traveling wheels of the two support plates respectively overlap the opposite sides of the lower flange of the lifting beam, it is beneficial to make the sliding parts slide smoothly along the length of the lifting beam, which facilitates the smooth movement of the hoisted pipe segments by moving the hand-operated hoist.
[0013] Preferably, a limiting bolt is threaded through the support plate, and the limiting bolt is abutted against the lifting beam.
[0014] By adopting the above technical solution, after the hand chain hoist is adjusted to the correct position, the limit bolt is tightened to make it abut against the lifting beam. The friction between the limit bolt and the lifting beam is used to restrict the movement of the sliding parts, so as to prevent the hand chain hoist from causing the pipe section to shift due to external load during the subsequent lifting and movement of the pipe section.
[0015] Preferably, the connecting rod is provided in two places, and the two connecting rods are respectively located at both ends of the lifting beam of the hoisting unit. The ends of the connecting rods are inserted through the opposite lifting beam, and the ends of the connecting rods are threadedly connected to two locking nuts through a threaded structure. The two locking nuts are respectively pressed against the opposite sides of the lifting beam.
[0016] By adopting the above technical solution, a stable connection between the connecting rod and the lifting beam is achieved by using two locking nuts, which facilitates better connection and positioning of the lifting beams of adjacent lifting units through the connecting rod.
[0017] Preferably, buffer plates are connected to both ends of the lifting beam, and the buffer plates at both ends of the lifting beam are respectively located between the two connecting rods, and flexible buffer pads are provided on the opposite side of the two buffer plates.
[0018] By adopting the above technical solution, when the sliding component moves along the lifting beam, the buffer plates at both ends of the lifting beam, together with the flexible buffer pads, can buffer and limit the sliding component, thereby preventing the sliding component from colliding with the connecting rods located at both ends of the lifting beam during the sliding process, which could lead to damage to the connecting rods and the sliding component.
[0019] Preferably, each of the longitudinal support rods has a sleeve welded to its outer periphery, and the sleeve is used for inserting the connecting rod.
[0020] By adopting the above technical solution, when transporting and storing the hoisting device, the connecting rod can be temporarily inserted into the connecting rod, and the connecting rod can be stored in the sleeve.
[0021] Preferably, the rope loop includes a steel wire rope, and both ends of the steel wire rope are provided with hooks, and the hooks are all sleeved on the hooks of the hand chain hoist.
[0022] By adopting the above technical solution, the wire rope is wrapped around and attached to the outer circumference of the pipe segment, and the two ends of the wire rope are attached to the hooks of the hand-operated hoist, thus completing the connection of the rope to the pipe segment.
[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. By attaching the sling to the pipe segment at the hoisting unit, the hoisting unit's hand-operated hoist pulls the sling upward to lift the pipe segment off the ground. The hoisting unit and the pipe segment are then moved using the casters at the bottom of the hoisting unit, facilitating the hoisting and movement of the pipe segment in areas with limited space.
[0024] 2. Using connecting rods to connect and limit the lifting beams of adjacent lifting units helps to improve the connection integrity of adjacent lifting units, thereby facilitating the more stable lifting of pipe segments by the lifting device.
[0025] 3. The hand-operated hoist can slide along the lifting beam via a sliding component, which facilitates the adjustment of the lateral position of the pipe segment by moving the hand-operated hoist along the lifting beam when lowering the pipe segment. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0033] This application discloses a pipeline hoisting device for municipal construction, referring to... Figure 1 and Figure 2 It includes two hoisting units 2. Each hoisting unit 2 includes a hoisting beam 21. Both ends of the hoisting beam 21 are vertically connected to supports 22. Several casters 23 are installed at the bottom of each support 22. Each hoisting beam 21 is equipped with a hand chain hoist 24. Each hand chain hoist 24 has a rope loop 25 attached to its hook for the pipe section 1 to be fitted.
[0034] When hoisting pipe segment 1, the rope loops 25 of each hoisting unit 2 are put onto pipe segment 1, and the rope loops 25 and pipe segment 1 are lifted by the hand hoist 24. Then, the hoisting unit is moved by the caster wheel 23 to hoist pipe segment 1.
[0035] Reference Figure 2 and Figure 3 The suspension beam 21 is an I-beam. The support frame 22 includes longitudinal support rods 221 and transverse support rods 222. The top of the longitudinal support rod 221 is connected to the suspension beam 21 via a connecting assembly. The transverse support rod 222 is vertically connected to the bottom of the longitudinal support rod 221, and the transverse support rod 222 and the longitudinal support rod 221 are arranged in an inverted "T" shape. The transverse support rod 222 increases the overall contact point between the support frame 22 and the ground, which helps to improve the structural stability of the support frame 22. A diagonal brace 223 is also provided between the transverse support rod 222 and the longitudinal support rod 221. The two ends of the diagonal brace 223 are welded to the transverse support rod 222 and the longitudinal support rod 221 respectively to improve the connection strength between the transverse support rod 222 and the longitudinal support rod 221.
[0036] Several casters 23 are evenly distributed at the bottom of the transverse support rod 222. In this embodiment, the casters 23 are specifically the existing casters 23 with brake structure. The casters 23 are fixed to the bottom of the transverse support rod 222 by bolts.
[0037] The connecting assembly includes a first connecting plate 210 and a second connecting plate 220. The first connecting plate 210 and the second connecting plate 220 are respectively welded to the near ends of the lifting beam 21 and the longitudinal support rod 221, and the first connecting plate 210 and the second connecting plate 220 are fitted together. The first connecting plate 210 and the second connecting plate 220 are connected and fixed by bolts and nuts to achieve a stable connection between the lifting beam 21 and the bracket 22.
[0038] Reference Figure 2 and Figure 3 The lifting beams 21 of adjacent lifting units 2 are connected by two connecting rods 3. The two connecting rods 3 are located at both ends of the lifting beams 21, and the ends of the connecting rods 3 are respectively inserted into the adjacent lifting beams 21. The ends of the connecting rods 3 are threaded with two locking nuts 31. The two locking nuts 31 are respectively tightened against the opposite sides of the corresponding lifting beams 21, so as to realize the stable connection between the connecting rods 3 and the lifting beams 21. The connection and reinforcement of adjacent lifting units 2 by the two connecting rods 3 is conducive to improving the connection integrity of adjacent lifting units 2, and thus makes the lifting device more stable when lifting pipe segments 1.
[0039] Reference Figure 2 and Figure 3 Each longitudinal support rod 221 has a sleeve 224 welded to its outer periphery. The sleeve 224 is used for inserting the connecting rod 3. When transporting and storing the hoisting device, the connecting rod 3 can be removed from the two adjacent lifting beams 21 and temporarily stored in the sleeve 224. This helps to reduce the overall hoisting space of the hoisting device, thus facilitating the transport and storage of the hoisting device.
[0040] Reference Figure 2 and Figure 4 The top of the hand chain hoist 24 is connected to a sliding member 241, which is slidably connected to the corresponding lifting beam 21. The sliding member 241 includes two support plates 2411, which are connected and fixed by several fixing rods 2410, with a gap between them. A lifting rod is also provided between the two support plates 2411, located at the bottom of the support plates 2411, with both ends of the lifting rod connected and fixed to the two support plates 2411 respectively. The hook at the top of the hand chain hoist 24 is hooked onto the lifting rod, achieving a stable connection between the hand chain hoist 24 and the sliding member 241.
[0041] Reference Figure 1 , 2 and Figure 4 Two support plates 2411 are located on opposite sides of the lifting beam 21. Several support shafts are fixed to each opposite side of the two support plates 2411. These support shafts are horizontally oriented and are rotatably connected to traveling wheels 2412 via bearings. The traveling wheels 2412 on opposite sides of the two support plates 2411 overlap the upper surfaces of opposite sides of the lower flange of the lifting beam 21, allowing the sliding member 241 to slide smoothly along the length of the lifting beam 21. When subsequently lifting the pipe segment 1 to the designated position, the lateral position of the pipe segment 1 can be adjusted by sliding the sliding member 241 along the lifting beam 21 using a hand-operated hoist 24, facilitating flexible placement of the pipe segment 1 into position.
[0042] Both support plates 2411 are threaded with limiting bolts 2413, and the web of the lifting beam 21 at the end of the limiting bolts 2413 is pressed against it. When the hand chain hoist 24 slides to the target position, the movement of the sliding component 241 can be restricted by tightening the limiting bolts 2413 and the friction between the limiting bolts 2413 and the web of the lifting beam 21. This prevents the sliding component 241 from sliding due to external loads during pipeline hoisting, which could cause displacement between the hand chain hoist 24 and the pipeline segment 1.
[0043] Reference Figure 3 and Figure 4 Buffer plates 211 are provided on opposite sides at both ends of the lifting beam 21. The buffer plates 211 at both ends of the lifting beam 21 are located between two connecting rods 3. The buffer plates 211 are vertically connected to fixed plates 2111, which are fixed to the web of the lifting beam 21 by bolts. Flexible buffer pads 212 are laid on opposite sides of the two buffer plates 211. The flexible buffer pads 212 are specifically rubber pads or sponge pads. When the sliding member 241 slides along the lifting beam 21 to the end of the lifting beam 21, the buffer plates 211 and the flexible buffer pads 212 can buffer and limit the sliding member 241, preventing the sliding member 241 from colliding with the connecting rods 3 located at the end of the lifting beam 21, which would cause damage to the connecting rods 3 and the sliding member 241.
[0044] Reference Figure 1 and Figure 5 The rope sling 25 includes a steel wire rope 251, with both ends of the steel wire rope 251 bent and tied together by rope clips 252 to form hook rings 253. Both hook rings 253 at both ends of the steel wire rope 251 are sleeved on the hooks of the hand chain hoist 24, thus connecting the rope sling 25 to the hand chain hoist 24.
[0045] When the rope loop 25 is put onto the outer circumference of the pipe section 1, the wire rope 251 can be unfolded and wrapped around the outer circumference of the pipe section 1 first, and then the two ends of the wire rope 251 can be hooked onto the hook of the hand chain hoist 24 to facilitate the connection operation between the rope loop 25 and the pipe section 1.
[0046] The implementation principle of this embodiment is as follows: When hoisting pipe segment 1, the rope loops 25 of the two hoisting units 2 are fitted onto the preset lifting points of pipe segment 1 and aligned with the outer wall of the pipe. Then, the rope loops 25 are pulled upwards using the hand-operated hoists 24 on the lifting beams 21 of the two hoisting units 2 to lift pipe segment 1 off the ground. The horizontal position of pipe segment 1 can be adjusted by sliding along the lifting beam 21 using the sliding member 241 at the top of the hand-operated hoist 24. Next, the hoisting unit 2 is moved by the universal wheels 23 at the bottom of the hoisting unit 2, and the two hoisting units 2 work together to move pipe segment 1 to the designated position; finally, pipe segment 1 is lowered into place using the hand-operated hoists 24.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
