Abstract
Description
Technical Field
[0001] This utility model relates to the field of beam hanging technology, specifically an electric telescopic beam hanging device. Background Technology
[0002] The electric telescopic beam is a key component of lifting and hoisting equipment. It uses electric drive to extend and retract the beam, and can flexibly adjust the length of the beam and the position of the lifting device according to the different specifications of the materials being hoisted and the actual operational needs.
[0003] In the prior art, such as the electric telescopic hanging beam disclosed in CN212452250U, the utility model uses two hydraulic cylinders to extend synchronously. At this time, the extension of the hydraulic cylinders on both sides causes the left and right main beams to move to both sides of the side plates respectively, which can extend the total length of the hanging beam, making the main beam telescopic, making the hanging beam more convenient to use, and expanding the range of applications of the main beam.
[0004] However, this device, by fitting the side plate between two hanging beams and placing the two hanging beams on the same axis, results in a relatively long base length for the hanging beams. Furthermore, the working coverage length of the hanging beams cannot be less than the length of the side plate plus the two hanging beams. This leads to a severe lack of adaptability of the electric telescopic hanging beam when facing complex and ever-changing actual working environments. Therefore, we propose an electric telescopic hanging beam. Utility Model Content
[0005] One of the technical problems this application aims to solve is that the foundation length of the hanging beam is relatively long, and the working area cannot be less than the length of the side plate plus two hanging beams.
[0006] To solve the above-mentioned technical problems, this application provides an electric telescopic hanging beam, including a sliding beam, with hanging beams slidably connected to both the upper and lower sides of the sliding beam. A driving component for driving the sliding beam to move is provided on the upper part of the hanging beam. Multiple evenly distributed and mirror-symmetrical rollers are provided on both the upper and lower sides of the sliding beam. A sliding groove is opened inside the hanging beam, and the rollers slide inside the sliding groove.
[0007] Preferably, the driving component includes a motor disposed at the edge of the hanging beam, a winding wheel disposed at the driving end of the motor, a guide wheel one disposed at the edge of the hanging beam, two guide wheels two disposed on both the front and rear sides of the middle of the sliding beam, a traction cable disposed on the outer periphery of the winding wheel, the traction cable passing through the guide wheel one and the two guide wheels two, the end of the traction cable away from the winding wheel being disposed inside the side of another hanging beam near the motor, and a stabilizing component for stabilizing the sliding beam and the lower hanging beam disposed inside the hanging beam.
[0008] Preferably, the stabilizing component includes a stabilizing plate disposed inside the hanging beam near the motor side, a second roller disposed on the side of the stabilizing plate away from the hanging beam, and a stabilizing groove formed on the side of the sliding beam near the first guide wheel, wherein the second roller and the stabilizing plate slide inside the stabilizing groove.
[0009] Preferably, the sliding beam is stepped and the cross-section of the sliding beam is convex.
[0010] Preferably, the hanging beam is concave.
[0011] Preferably, the inner wall edge of the hanging beam is provided with a plurality of evenly distributed support blocks, the support blocks being arch-shaped.
[0012] Preferably, the cross-section of the sliding beam is set to a mirror-symmetrical concave shape, and the cross-section of the hanging beam is set to a "mountain" shape.
[0013] This utility model has at least the following beneficial effects:
[0014] 1. Through the cooperation of the motor, winding reel, traction cable, guide wheel one, and guide wheel two, the lower hanging beam can be pulled to slide. The upper and lower hanging beams are fitted together by the stepped sliding beam, which can reduce the length occupied by the two hanging beams and increase the extension distance of the hanging beams. The compression of the traction cable can cause guide wheel two to push the sliding beam and the lower hanging beam to move in the same direction, thereby allowing the sliding beam and the lower hanging beam to slide outward. The reverse traction of the winding reel can shorten the sliding beam and the lower hanging beam in the same way, thereby achieving the function of shorter space occupation and longer sliding coverage.
[0015] 2. By using the stabilizing plate and rollers installed at the edge of the hanging beam, the weight of the hanging beam acting on the edge of the sliding beam can be shared when the hanging beam slides. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: an electric telescopic hanging beam, including a sliding beam 2, with a hanging beam 1 slidably connected to both the upper and lower sides of the sliding beam 2, a driving component 3 for driving the sliding beam 2 to move is provided on the upper part of the hanging beam 1, and multiple evenly distributed and mirror-symmetrical rollers 21 are provided on both the upper and lower sides of the sliding beam 2, and a sliding groove 22 is opened inside the hanging beam 1, with the rollers 21 sliding inside the sliding groove 22.
[0024] The sliding beam 2 serves as the main load-bearing and sliding structure of the device. It allows the lower hanging beam 1 to slide under the sliding beam 2, and at the same time, it allows the sliding beam 2 to slide inside the upper hanging beam 1. Through the interlaced structural distribution, the hanging beam 1 and the sliding beam 2 can achieve a longer sliding length with minimal structural space. The roller 21 can reduce the friction when the sliding beam 2 and the hanging beam 1 move relative to each other.
[0025] Furthermore, the driving component 3 includes a motor 31 located at the edge of the hanging beam 1. The driving end of the motor 31 is provided with a winding wheel 32. A guide wheel 33 is provided at the edge of the hanging beam 1. Two guide wheels 35 are provided on both the front and rear sides of the middle of the sliding beam 2. A traction cable 34 is provided on the outer periphery of the winding wheel 32. The traction cable 34 passes through the guide wheel 33 and the two guide wheels 35. One end of the traction cable 34 away from the winding wheel 32 is located inside the side of another hanging beam 1 near the motor 31. A stabilizing component 4 for stabilizing the sliding beam 2 and the lower hanging beam 1 is provided inside the hanging beam 1.
[0026] Motor 31 drives take-up reel 32 to rotate. Take-up reel 32 can pull and wind up traction cable 34. Guide wheel 1 33 and guide wheel 2 35 can guide the direction of traction cable 34 and prevent traction cable 34 from getting tangled in the gap between hanging beam 1 and sliding beam 2. When traction cable 34 is wound up, it can drive another hanging beam 1 to move. The above structure is arranged in two sets in a mirror distribution, thereby realizing the function of sliding extension and retraction of the lower hanging beam 1 and sliding beam 2.
[0027] Furthermore, the stabilizer 4 includes a stabilizer plate 41 disposed inside the hanging beam 1 near the motor 31. A roller 42 is disposed on the side of the stabilizer plate 41 away from the hanging beam 1. A stabilizer groove 43 is provided on the side of the sliding beam 2 near the guide wheel 33. The roller 42 and the stabilizer plate 41 slide inside the stabilizer groove 43.
[0028] The stabilizing plate 41 can be connected to the roller 42, which can slide inside the stabilizing groove 43. When the hanging beam 1 slides, the position of the roller 42 inside the stabilizing groove 43 changes, and the weight of the hanging beam 1 acting on the edge of the sliding beam 2 can be shared by the stabilizing plate 41 and the roller 42.
[0029] Furthermore, the sliding beam 2 is stepped and its cross-section is convex.
[0030] Furthermore, the hanging beam 1 is concave.
[0031] The interlocking concave-convex structure of the hanging beam 1 and the sliding beam 2 makes their operation more stable, and the concave-convex cross-section can further reduce the overall weight of the hanging beam 1 and the sliding beam 2, and increase the overall structural strength of the hanging beam 1 and the sliding beam 2.
[0032] Furthermore, multiple evenly distributed support blocks 5 are provided at the inner edge of the hanging beam 1, and the support blocks 5 are arch bridge shaped.
[0033] The support block 5 can serve as a load-bearing support inside the hanging beam 1. The support of the support block 5 can make the overall force of the hanging beam 1 more balanced, preventing the hanging beam 1 from cracking due to uneven force.
[0034] When the device is started, the two motors 31 start and drive the winding wheel 32 to rotate. The upper winding wheel 32 pulls and winds the upper traction cable 34, while the lower winding wheel 32 releases the traction cable 34. The upper traction cable 34, guided by guide wheel 1 33 and guide wheel 2 35, can pull the lower hanging beam 1 to slide. The compression of the traction cable 34 can push the sliding beam 2 and the lower hanging beam 1 to move in the same direction, thereby allowing the sliding beam 2 and the lower hanging beam 1 to slide outward. At this time, roller 1 21 can guide the sliding beam 2 to slide inside the upper hanging beam 1, and the lower hanging beam 1 to slide under the sliding beam 2. The winding wheel 32 pulls in the opposite direction, which can cause the sliding beam 2 and the lower hanging beam 1 to slide and shorten in the same way. Thus, the sliding beam 2 and the lower hanging beam 1 can achieve the function of sliding and extending simultaneously.
[0035] Example 2: Please refer to Figure 5 Based on Embodiment 1, this utility model provides another technical solution: the cross section of the sliding beam 2 is set as a mirror-symmetrical concave shape, and the cross section of the hanging beam 1 is set as a "mountain" shape;
[0036] By further interlacing the hanging beam 1 and the sliding beam 2, the fitting density of the hanging beam 1 and the sliding beam 2 can be increased, the structural strength of the hanging beam 1 and the sliding beam 2 can be increased, and the overall weight of the hanging beam 1 and the sliding beam 2 can be reduced.
