Description
Technical Field
[0001] The utility model relates to the technical field of mining metallurgical electromechanical equipment, in particular to a lifting device for processing mining metallurgical electromechanical equipment. Background Art
[0002] Mines include coal mines, metal mines, non-metallic mines, building materials mines and chemical mines, etc. The scale of mines (also known as production capacity) is usually expressed in annual output or daily output. The annual output is the amount of ore produced by the mine each year. Nowadays, with the increasing scale of mining, the output of ore is also increasing. In order to save manpower, a large amount of mining metallurgical electromechanical equipment needs to be invested in mining operations. During the processing of mining metallurgical electromechanical equipment, it is necessary to use equipment processing lifting devices to lift it for the convenience of production and transportation.
[0003] At present, most lifting devices cannot lift smoothly during the lifting process, the lifting object is prone to swing too much, and the distance between the connected hooks cannot be controlled. At the same time, the crane is bulky and inconvenient to move, making it difficult to transfer between the production site and the construction site, delaying the work progress. Utility Model Content
[0004] The technical problem to be solved by the utility model is: in view of the above existing problems, a lifting device for processing mining and metallurgical electromechanical equipment is provided.
[0005] The technical solution adopted by the utility model is: a balanced hanging beam, characterized in that it comprises:
[0006] Main beam;
[0007] Suspension components, respectively installed on both sides of the center of the main beam, for hoisting the device;
[0008] A balancing block is arranged above the main beam, and two sides of the balancing block are respectively connected to the corresponding suspension components via side-pull cables to maintain the balance of the main beam;
[0009] The adjusting components are respectively installed on both sides of the center of the main beam and connected to the corresponding suspension components, and are used to control the movement of the suspension components along the axis of the main beam, so as to adjust the distance between the two groups of suspension components.
[0010] Through the above-mentioned technical means, firstly, both sides of the balance block are connected to the suspension components on both sides of the center of the main beam through side-pull cables. The main beam can provide a larger support area. Compared with the traditional single lifting point, the two sets of suspension components can reduce the swing amplitude of the hoisted object. Secondly, when the lifting of the suspension component is unstable, the adjustment component inside the main beam is used to adjust the spacing of the suspension components to keep the equipment hoisted on the main beam balanced, thereby avoiding damage to the equipment during lifting.
[0011] In some embodiments, the adjustment component includes an adjusting wheel, a screw and a movable central shaft. The screw is installed on both sides of the center of the main beam. The ends of the two sections of the screw away from the center of the main beam are connected with adjusting wheels. The outer surfaces of the two sections of the screw are formed with external threads. The two sections of the screw are each sleeved and threadedly connected with the movable central shaft. The movable central shaft is connected to the corresponding suspension component, and the position of the corresponding suspension component can be adjusted by rotating the adjusting wheel.
[0012] Through the above-mentioned technical means, the end of each screw section is connected to an adjusting wheel for driving it to rotate, and each screw section is threadedly connected to a movable middle shaft. The corresponding screw is driven to rotate by rotating the adjusting wheel. Since the movable middle shaft on the screw is threadedly connected to the screw, and the movable middle shaft is connected to the corresponding suspension assembly, the movable middle shaft produces a relative displacement along the axial direction of the main beam under the rotation of the screw, and the movable middle shaft further drives the suspension assembly to move, thereby adjusting the spacing between the two groups of suspension assemblies and adjusting the hanging position of the corresponding hoisting object of the suspension assembly.
[0013] In some embodiments, the suspension assembly includes a lifting ear, a connecting frame, a mounting seat and a lifting hook. The connecting frame is slidably installed on the main beam, the connecting frame and the movable central axis are interconnected, the top of the connecting frame is connected to the lifting ear, the lifting ear is connected to the corresponding side-pull cable, the bottom of the connecting frame is connected to the mounting seat, and the lifting hook is installed on the mounting seat.
[0014] Through the above-mentioned technical means, the lifting ears on the top of the two connecting frames are connected to the side-pull cables, so that the two sets of suspension components can be pulled by the corresponding side-pull cables. When the movable central axis moves, the movable central axis can drive the corresponding connecting frame to slide along the axial direction of the main beam. According to the actual needs of the construction, the lifting hook at the bottom of the connecting frame is adjusted away from or close to the center of the main beam.
[0015] In some embodiments, a latch is provided between the connection frame and the adjustment component, so that the connection frame and the adjustment component are latched together by the latch.
[0016] Another technical solution adopted by the utility model is: a lifting device for mining and metallurgical electromechanical equipment processing, characterized in that it includes:
[0017] A moving and supporting assembly capable of providing a supporting platform for the loading device and driving the supporting platform to move;
[0018] A bracket assembly, mounted on the support platform, for providing traction guidance and support;
[0019] Balanced hanging beam;
[0020] A traction assembly is installed on the support platform, supported by the top of the bracket assembly, and connected to the balancing block of the balancing beam, so as to traction the balancing beam.
[0021] Through the above-mentioned technical means, the support platform is used to load the bracket assembly and the traction assembly, the traction assembly is connected to the balancing block through the bracket assembly, the traction assembly is used to pull the balancing beam and control its lifting, the bracket assembly is used to provide traction support and guidance to the traction assembly, and the balancing beam can lift the hoisted object.
[0022] In some embodiments, the support assembly includes a base, a support frame and a winding wheel. The base is installed on the support platform, the support frame is connected to the base, the winding wheels are respectively installed at both ends of the top of the support frame, and the traction assembly is connected to the balance beam via the winding wheel.
[0023] In some embodiments, a rotating pile is provided between the base and the support frame, and the support frame can rotate around the axis of the base via the rotating pile.
[0024] Through the above-mentioned technical means, the supporting frame is able to rotate relative to the base by utilizing rotating piles, so that the supporting frame drives the balancing beam to move through the traction assembly. The movement of the balancing beam can adjust the lifting direction of the suspension assembly. Compared with lifting the balancing beam at a single position, the lifting working range of the balancing beam is further improved.
[0025] In some embodiments, the traction assembly includes a fixed frame, a lifting wheel, a rope drum and a traction cable. Two groups of the fixed frames are installed on the supporting platform. The rope drum is connected between the two groups of the fixed frames. One end of the traction cable is connected to the rope drum, and the other end of the traction cable is connected to the balance block through the bracket assembly. The lifting wheels are installed at both ends of the rope drum, and the lifting wheels are used to control the traction movement of the traction cable on the balance beam.
[0026] In some embodiments, the moving and supporting assembly includes a transport chassis and driving wheels, the support assembly and the traction assembly are installed on the top of the transport chassis, and the driving wheels are installed on the bottom of the transport chassis.
[0027] Through the above-mentioned technical means, the support assembly and the traction assembly are loaded on the transport chassis, and the driving wheels provided at the bottom of the transport chassis can enable the lifting device to be moved as a whole on the construction site. According to the actual needs on site, the lifting device can be transferred between the production site and the construction site, thereby making the use of the device more flexible.
[0028] The beneficial effects of the utility model are:
[0029] 1. Two sets of suspension components are set on the main beam to lift the electromechanical equipment. Compared with the single lifting point of the traditional hook, the main beam increases the supporting area of the lifting. The two sets of suspension components can share the suspension pressure on the electromechanical equipment, which not only avoids damage to the electromechanical equipment due to single-point stress concentration during the lifting process, but also reduces the swing amplitude of the hoisted object, making the lifting process more stable.
[0030] 2. Before lifting, the suspension assembly is driven to move on the main beam through the adjustment assembly, and then the distance between the two sets of suspension assemblies is adjusted. The suspension position is flexibly adjusted to adapt to the position of the lifting lugs of the electromechanical equipment, so that the hoisted object can maintain balance during the lifting process. With the help of the adjustment assembly, the lifting device has a wider application range and can be adapted to more types of electromechanical equipment.
[0031] 3. The transport chassis carries the bracket assembly and the traction assembly. The driving wheels at the bottom of the transport chassis can facilitate the flexible movement of the lifting device. The lifting device can be adjusted to transfer its position between the production site and the construction site according to actual conditions to improve the transportation efficiency.
[0032] 4. By setting a rotating pile between the base and the support frame, the rotating pile can drive the support frame to rotate, and the rotation of the support frame drives the balance beam to move, thereby adjusting the suspension position of the suspension component on the balance beam, making the use of the lifting device more flexible and the application of the lifting device wider.

DETAILED DESCRIPTION
[0039] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below in conjunction with specific embodiments.
[0040] Embodiment 1:
[0041] Combination Figure 1 and Figure 2 As shown, this embodiment is a balanced suspension beam, including a main beam 13, a suspension assembly, a balance block 11 and an adjustment assembly. Figure 2 As shown, the adjustment assembly includes a movable middle shaft 18, a screw rod 17, and an adjustment wheel 14. The screw rods 17 are installed at both ends of the center of the main beam 13. The screw rods 17 are arranged along the axis direction of the main beam 13, and the adjustment wheels 14 are installed at the ends of the two sections of the screw rods 17 away from the center of the main beam 13. An external thread is formed on the outer surface of the screw rod 17, and the movable middle shaft 18 is sleeved on the screw rod 17. The inner wall of the movable middle shaft 18 is formed with an internal thread that matches and connects with the external thread of the screw rod 17, so that the movable middle shaft 18 and the screw rod 17 are connected by a thread.
[0042] like Figure 2 As shown, the suspension assembly includes a lifting lug 20, a connecting frame 16, a mounting seat 19 and a lifting hook 15. The two ends of the center of the main beam 13 are slidably sleeved with a connecting frame 16. The connecting frame 16 can slide along the axial direction of the main beam 13. The top of the connecting frame 16 is provided with a lifting lug 20, and the bottom of the connecting frame 16 is provided with a mounting seat 19. The mounting seat 19 is connected to the lifting hook 15. A balance block 11 is provided above the main beam 13. Side-pull cables 12 are connected to both sides of the balance block 11. The balance block 11 is connected to the lifting lugs 20 of the two groups of connecting frames 16 on the main beam 13 through two side-pull cables 12, respectively, so that the main beam 13 can remain stable even during the lifting process, preventing it from tilting during the lifting process and causing accidents, thereby improving the safety of the main beam 13 in lifting objects. At the same time, the two groups of connecting frames 16 are connected to the corresponding movable middle shaft 18 on the screw rod 17. Specifically, in this embodiment, a clamping bolt is provided between the connection frame 16 and the movable middle shaft 18 , so that the connection frame 16 and the movable middle shaft 18 are clamped together via the clamping bolt.
[0043] By driving the adjusting wheel 14, the adjusting wheel 14 can drive the corresponding screw 17 to rotate around its own axis. Since the movable middle shaft 18 is clamped with the connecting frame 16, the connecting frame 16 restricts the rotation of the movable middle shaft 18. Based on the threaded connection between the movable middle shaft 18 and the screw 17, the rotation of the screw 17 causes the movable middle shaft 18 to produce relative displacement along the axial direction of the screw 17, and then the movable middle shaft 18 drives the connecting frame 16 clamped thereto to slide along the axial direction of the main beam 13, so as to achieve the adjustment of the distance between the two sets of lifting hooks 15 by rotating the adjusting wheel 14.
[0044] Embodiment 2:
[0045] Combination Figure 3 and Figure 4 As shown, this embodiment is a lifting device for processing mining and metallurgical electromechanical equipment, including a moving and supporting assembly, a bracket assembly, a traction assembly and a balancing beam. The moving and supporting assembly includes a transport chassis 1 and a driving wheel 2. A supporting platform is formed on the top of the transport chassis 1, and a bracket assembly and a traction assembly are installed on the supporting platform. The traction assembly is connected to the balancing beam via the bracket assembly. Four sets of driving wheels 2 are installed at the bottom of the transport chassis 1. With the help of the driving wheels 2, the lifting device can be transferred between the production site and the construction site according to the actual construction needs, thereby improving the efficiency of the transportation work.
[0046] Further, such as Figure 4 As shown, the bracket assembly includes a base 9, a rotating pile 8, a support frame 7 and a winding wheel 10. The base 9 is detachably connected to the transport chassis 1 via a connecting shaft, and the base 9 is connected to the support frame 7 via the rotating pile 8. The winding wheels 10 are respectively installed at both ends of the top of the support frame 7. Through the rotating pile 8, the support frame 7 can rotate around the axis of the base 9.
[0047] The traction assembly includes a fixed frame 3, a lifting wheel 4, a rope drum 5 and a traction cable 6. Two sets of fixed frames 3 are installed on the support platform, and a rope drum 5 is installed between the two sets of fixed frames 3. Lifting wheels 4 for controlling the rope drum 5 are installed on the side walls of the two sets of fixed frames 3, and a traction cable 6 is wound around the rope drum 5. One end of the traction cable 6 is connected to the rope drum 5, and the other end of the traction cable 6 is wound around the two sets of winding wheels 10 on the support frame 7 in sequence and connected to the inside of the balance block 11 of the balance beam.
[0048] The implementation principle of the lifting device for mining and metallurgical electromechanical equipment processing in the embodiment of the utility model is:
[0049] The transport chassis 1 is used to load the traction assembly and the bracket assembly. When the lifting work is carried out, the driving wheel 2 drives the lifting device to move to the electromechanical equipment. The lifting wheel 4 drives the traction cable 6 on the rope drum 5, and the traction cable 6 is used to pull the balance beam. The electromechanical equipment can be lifted by the lifting hook 15 on the balance beam. The two sets of lifting hooks 15 respectively lift the lifting ears 20 at both ends of the electromechanical equipment.
[0050] During lifting, the distance between the two groups of connecting frames 16 can be adjusted by rotating the adjusting wheel 14, which drives the screw 17 to rotate. The movable central axis 18 on the screw 17 moves due to the action of the thread. The movable central axis 18 and the connecting frame 16 are connected by a bolt, so that the movable central axis 18 can drive the connecting frame 16 to move, thereby adjusting the distance between the two groups of lifting hooks 15, so that the positions of the two groups of lifting hooks 15 correspond to the positions of the lifting ears 20 of the electromechanical equipment.
[0051] The balancing block 11 can maintain the balance of the main beam 13, and the main beam 13 can be pulled by the side-pull cables 12 on both sides, so that the main beam 13 can also remain stable during the lifting process. During the lifting process, the direction of the suspension assembly is adjusted by rotating the rotating pile 8 at the bottom of the support frame 7, so that the lifting device can drive the electromechanical equipment to be transported in a wider range.
[0052] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
