Description

Technical Field

[0001] The utility model relates to the technical field of hoisting machinery, in particular to a coordinated hoisting control device and a crane. Background Art

[0002] Crane refers to a multi-action lifting machine that can lift and carry heavy objects vertically and horizontally within a certain range. Also known as a crane, some lifting equipment has the working characteristic of intermittent movement, that is, the corresponding mechanisms of taking materials, moving, unloading and other actions work alternately in one working cycle. The development and use of cranes in the market are becoming more and more extensive.

[0003] In the prior art, for short-distance lifting, multiple independently controlled crane arms are usually set on the lifting platform, and a large object is tied to multiple crane arms. Each crane arm is raised synchronously through an independent control unit. However, this method requires the workers to cooperate with each other and command in order to achieve uniformity as much as possible when multiple crane arms are raised. Otherwise, the inconsistent rising frequency will cause the object to tilt and affect the stability of the lifting. If the cooperation of sensors, servos and crane arm control modules is used to achieve synchronous lifting, the cost is too high for short-distance lifting. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a collaborative lifting control device, which aims to solve the problem in the prior art that workers need to cooperate consistently and give commands in a measured manner in order to achieve uniformity in the raising of multiple crane arms as much as possible. Otherwise, the inconsistent raising frequencies will cause the object to tilt and affect the stability of the lifting. If sensors, servos and crane arm control modules are used to achieve synchronous lifting, the cost will be too high for short-distance lifting.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] A collaborative lifting control device includes a lifting platform, a supporting mechanism arranged on the lifting platform, a driving mechanism for controlling the vertical movement of the supporting mechanism, a pulley assembly slidably arranged on the supporting mechanism, and a lifting assembly arranged on the pulley assembly, the pulley assembly includes a sliding rod and a pulley body rotatably arranged on the sliding rod, a sliding groove is provided on the supporting mechanism, the sliding rod slides along the sliding groove to make the pulley body move horizontally, a stabilizing assembly is provided between the supporting mechanism and the lifting assembly, the stabilizing assembly includes a first articulated seat arranged on the supporting mechanism, a second articulated seat arranged on the lifting assembly, and a first telescopic rod whose two ends are respectively rotatably connected to the first articulated seat and the second articulated seat.

[0007] According to one aspect of the above technical solution, the support mechanism includes a support plate connected to the driving mechanism, two support rods arranged on the support plate and passing through the hoisting platform, two sliding plates respectively arranged on the two support rods, and a second telescopic rod arranged between the sliding plate and the hoisting platform, and the slide groove is arranged on the sliding plate.

[0008] According to one aspect of the above technical solution, the driving mechanism includes a multi-stage hydraulic telescopic rod arranged on the lifting platform, and the free end of the multi-stage hydraulic telescopic rod is fixedly connected to the support plate.

[0009] According to one aspect of the above technical solution, the hoisting assembly includes a fixed block arranged on the hoisting platform, and a sling arranged on the fixed block, and the sling is wound around the pulley body.

[0010] According to one aspect of the above technical solution, the hoisting platform is provided with an avoidance hole for the horizontal movement of the sling.

[0011] According to one aspect of the above technical solution, a hook for hoisting objects is provided at the end of the sling.

[0012] According to one aspect of the above technical solution, the multi-stage hydraulic telescopic rod includes a cylinder body located above the hoisting platform, and a multi-section telescopic rod connected to the cylinder body, and the multi-section telescopic rod passes through the hoisting platform and is located below the hoisting platform.

[0013] The present invention also provides a crane, comprising the cooperative lifting control device as described above.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By arranging a supporting mechanism on the lifting platform, and arranging a pulley assembly on the supporting mechanism and a lifting assembly on the pulley assembly, when it is necessary to lift large objects, the supporting mechanism can be raised by the driving mechanism, and the supporting mechanism can lift up the pulley assemblies and the lifting assemblies on both sides. Due to the characteristics of the pulley assembly, the two lifting assemblies can be raised synchronously to realize coordinated lifting of the objects. When it is necessary to adjust the position of the lifting assembly according to the size of the object, the sliding rod can be pushed to make the sliding rod drive the pulley body to move horizontally in the sliding groove, so that the pulley body drives the lifting assembly to move horizontally to adjust the position. At the same time, a stabilizing assembly is arranged between the supporting mechanism and the lifting assembly. When the lifting assembly and the supporting mechanism rise, the first telescopic rod will rise synchronously. The shaking generated during the rising process of the lifting assembly will be limited by the existence of the first telescopic rod, so that its shaking distance shall not exceed the maximum distance of the first telescopic rod, so as to control the shaking generated when the lifting assembly rises. At the same time, the lifting assembly will also drive the extension of the first telescopic rod when adjusting its position horizontally to ensure stability.

[0016] The utility model can realize synchronous lifting of objects and adjust the position of the lifting point and improve the stability of the lifting. BRIEF DESCRIPTION OF THE DRAWINGS

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] See also Figures 1 to 4 , shown is a cooperative lifting control device in the first embodiment of the utility model, including a lifting platform 10, a supporting mechanism 20 arranged on the lifting platform 10, a driving mechanism 60 for controlling the vertical movement of the supporting mechanism 20, a pulley assembly 30 slidably arranged on the supporting mechanism 20, and a lifting assembly 40 arranged on the pulley assembly 30, the pulley assembly 30 includes a slide bar 31, and a pulley body 32 rotatably arranged on the slide bar 31, a slide groove 26 is provided on the supporting mechanism 20, the slide bar 31 slides along the slide groove 26 to make the pulley body 32 move horizontally, a stabilizing assembly 50 is provided between the supporting mechanism 20 and the lifting assembly 40, the stabilizing assembly 50 includes a first articulated seat 51 arranged on the supporting mechanism 20, a second articulated seat 53 arranged on the lifting assembly 40, and a first telescopic rod 52 whose two ends are rotatably connected to the first articulated seat 51 and the second articulated seat 53 respectively.

[0028] It can be understood that the utility model sets a support mechanism 20 on the lifting platform 10, sets a pulley assembly 30 on the support mechanism 20, and sets a lifting assembly 40 on the pulley assembly 30. When it is necessary to lift a large object, the support mechanism 20 can be raised by the driving mechanism 60, and the support mechanism 20 can lift the pulley assemblies 30 and the lifting assembly 40 on both sides. Due to the characteristics of the pulley assembly 30, the two lifting assemblies 40 can be raised synchronously to achieve coordinated lifting of the object. When it is necessary to adjust the position of the lifting assembly 40 according to the size of the object, the slide bar 31 can be pushed to make the slide bar 31 drive the pulley body 32 moves horizontally in the slide groove 26, so that the pulley body 32 drives the lifting assembly 40 to move horizontally to adjust the position. At the same time, a stabilizing assembly 50 is arranged between the supporting mechanism 20 and the lifting assembly 40. When the lifting assembly 40 and the supporting mechanism 20 rise, the first telescopic rod 52 will rise synchronously. The shaking generated during the rising process of the lifting assembly 40 will be limited due to the existence of the first telescopic rod 52, so that the shaking distance shall not exceed the maximum distance of the first telescopic rod 52, so as to control the shaking generated during the rising of the lifting assembly 40. At the same time, when the lifting assembly 40 is adjusted in the horizontal position, it will also drive the extension of the first telescopic rod 52 to ensure stability.

[0029] The utility model can realize synchronous lifting of objects and adjust the position of the lifting point and improve the stability of the lifting.

[0030] Specifically, in this embodiment, the support mechanism 20 includes a support plate 21 connected to the driving mechanism 60, two support rods 22 arranged on the support plate 21 and passing through the lifting platform 10, two sliding plates 24 respectively arranged on the two support rods 22, and a second telescopic rod 25 arranged between the sliding plate 24 and the lifting platform 10, and the slide groove 26 is arranged on the sliding plate 24.

[0031] It can be understood that when it is necessary to hoist items, the support plate 21 is driven by the driving mechanism 60 to drive the two support rods 22 to rise, and the two support rods 22 drive the two sliding plates 24 to rise, and the two sliding plates 24 drive the hoisting components 40 thereon to rise, so as to pull up the items synchronously. The position of the hoisting components 40 can be adjusted by sliding the sliding rod 31 along the sliding groove 26 to find the most suitable fixing point.

[0032] Furthermore, the driving mechanism 60 includes a multi-stage hydraulic telescopic rod 63 arranged on the lifting platform 10, and the free end of the multi-stage hydraulic telescopic rod 63 is fixedly connected to the support plate 21; the multi-stage hydraulic telescopic rod 63 includes a cylinder body 61 located above the lifting platform 10, and a multi-section telescopic rod 62 connected to the cylinder body 61, and the multi-section telescopic rod 62 passes through the lifting platform 10 and is located below the lifting platform 10, and the support plate 21 can be controlled to move up and down through the action of the multi-stage hydraulic telescopic rod 63.

[0033] Furthermore, the lifting assembly 40 includes a fixed block 41 arranged on the lifting platform 10, and a sling 42 arranged on the fixed block 41, and the sling 42 is wound around the pulley body 32; the lifting platform 10 is provided with an avoidance hole 27 for the horizontal movement of the sling 42; the end of the sling 42 is provided with a hook 43 for lifting objects.

[0034] It can be understood that the hook 43 is first hooked onto the rope tied to the object. When the two sliding plates 24 drive the two pulley bodies 32 to rise, the slings 42 on both sides will be driven to rise synchronously, and then the objects hoisted on the two slings 42 will be driven to rise synchronously. The purpose of the avoidance hole 27 is to avoid interference with the sling 42 when the sling 42 moves horizontally.

[0035] In summary, the collaborative lifting control device in the above embodiment of the utility model can not only realize synchronous lifting of objects, but also adjust the position of the lifting point and improve the stability of the lifting.

[0036] The second embodiment of the utility model provides a crane, which comprises the cooperative lifting control device in the first embodiment.
