Description

Technical Field

[0001] This utility model relates to the field of substation engineering construction technology, specifically to a hoisting machine for substation engineering construction. Background Technology

[0002] The use of hoisting machines is crucial in the construction of substation projects. They are responsible for safely and accurately hoisting heavy equipment or components to designated locations, and are a key factor in ensuring project progress and quality. However, existing hoisting machines used in substation construction suffer from significant inconveniences regarding steel cable lubrication.

[0003] Traditional hoisting machines' steel cables are prone to performance degradation due to friction and wear during use, potentially even posing safety hazards. Regular lubrication is essential to maintain the steel cables' good condition and extend their service life. However, existing lubrication methods often rely on manual operation, which is not only inefficient but also makes it difficult to ensure even and timely lubrication. Furthermore, manual lubrication carries safety risks, as operators must work near the hoisting machine's operating area, and even a slight mishap could lead to an accident.

[0004] Chinese Patent Publication No. CN221894574U discloses a safety hoisting machine for substation construction, comprising a base plate with a first sliding groove on its upper surface. A movable plate is movably connected to the upper surface of the base plate, and a second bracket is fixedly connected to the front of the upper surface of the movable plate. A first motor is fixedly connected to the right side of the second bracket, and a rotating shaft is keyed to the left output shaft of the first motor. The outer sides of both ends of the rotating shaft are movably connected to the second bracket, and a wheel is fixedly connected to the middle outer side of the rotating shaft. This invention, by incorporating a reading meter, can detect the mass of the hoisted object, preventing it from exceeding the hoisting machine's lifting capacity and thus avoiding overloading and potential hazards. The inclusion of a first and second stabilizing plate ensures the stability of the hoisting machine during the hoisting process, preventing the hoisted object from swaying and thus avoiding potential dangers.

[0005] However, in practical use, the above structure makes it difficult to lubricate the steel rope when using a wire rope crane. First, the lack of effective lubrication results in greater frictional resistance during operation, which not only increases energy consumption but also accelerates the wear of the rope surface. Over time, the worn rope surface gradually becomes rough, further exacerbating friction with pulleys and other components. Utility Model Content

[0006] To address the aforementioned issues, a hoisting machine for substation construction is provided, which solves the problem of inconvenient lubrication of steel ropes through a lubrication mechanism.

[0007] To address the problems of existing technologies, this utility model provides a hoisting machine for substation construction, comprising a housing, a linear drive mounted on the top of the housing, a pair of movable blocks slidably mounted on the top of the housing, a hook mounted between the pair of movable blocks, and a steel cable crane mounted on the top of the movable blocks and connected to the hook. The hoisting machine also includes a lubrication mechanism and a contact mechanism. The lubrication mechanism is mounted on the top of the movable blocks and includes a mounting plate, a displacement block, and a lubrication block. The mounting plate is mounted on the top of the pair of movable blocks. The displacement block is slidably mounted on the top of the mounting plate. The top of the mounting plate has a travel groove for the displacement block to slide. The lubrication block is mounted on the top of the displacement block. The contact mechanism is located beside the movable blocks.

[0008] Preferably, the lubrication mechanism further includes a mounting plate, a rotating rod, and a transmission belt; the mounting plate is installed beside the mounting plate and is located above the housing; the rotating rod is rotatably installed beside the mounting plate and is located beside the mounting plate; the transmission belt is located beside the linear drive, one end of the transmission belt is connected to the output end of the linear drive, and the other end of the transmission belt is connected to the rotating rod.

[0009] Preferably, the lubrication mechanism further includes a connecting rod; the connecting rod is rotatably disposed outside the rotating rod, one end of the connecting rod is rotatably connected to the rotating rod, and the other end of the connecting rod is rotatably connected to the displacement block.

[0010] Preferably, the lubrication mechanism further includes fasteners; the top of the displacement block has an opening for inserting the lubricating block; the fasteners are a pair and are rotatably disposed on both sides of the displacement block, and the fasteners can be screwed in to abut the lubricating block against the top of the displacement block.

[0011] Preferably, the lubrication mechanism further includes fasteners; the top of the displacement block has an opening for inserting the lubricating block; the fasteners are a pair and are rotatably disposed on both sides of the displacement block, and the fasteners can be screwed in to abut the lubricating block against the top of the displacement block.

[0013] Preferably, the abutting mechanism includes a hydraulic cylinder and an ejector block; the hydraulic cylinder has a pair and is respectively disposed on the side of the pair of movable blocks; the ejector block has a pair and is respectively disposed at the output end of the hydraulic cylinder.

[0014] Preferably, the top of the ejector block has an opening for the steel rope to pass through.

[0015] The advantages of this utility model compared to the prior art are:

[0016] 1. By setting up a lubrication mechanism, the displacement block can slide back and forth along the mounting plate when the steel rope crane is started. During the sliding process, the lubrication block is driven to intermittently contact the steel rope, thereby achieving intermittent contact lubrication of the steel rope and improving the service life of the steel rope.

[0017] 2. This utility model uses a fastener to place the lubricating block into an opening at the top of the displacement block, and then rotates the fastener until the lubricating block abuts against the top of the displacement block. This allows for quick installation and removal of the lubricating block.

[0018] 3. By setting up an abutment mechanism, this utility model indirectly reduces the swaying amplitude of the steel rope, which helps to improve the stability of the hoisting process. Attached Figure Description

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] See Figures 1-4 As shown, a hoisting machine for substation construction includes a housing 1, a linear drive 2 mounted on top of the housing 1, a pair of movable blocks 3 slidably mounted on top of the housing 1, a hook 4 positioned between the pair of movable blocks 3, and a steel cable crane 5 mounted on top of the movable blocks 3 and connected to the hook 4. The hoisting machine also includes a lubrication mechanism 6 and a contact mechanism 7. The lubrication mechanism 6 is located on top of the movable blocks 3 and includes a mounting plate 61, a displacement block 62, and a lubrication block 63. The mounting plate 61 is located on top of the pair of movable blocks 3. The displacement block 62 is slidably mounted on top of the mounting plate 61. The top of the mounting plate 61 has a travel groove for the displacement block 62 to slide. The lubrication block 63 is located on top of the displacement block 62. The contact mechanism 7 is located beside the movable blocks 3.

[0028] The output end of the linear actuator 2 is equipped with a lead screw threadedly connected to the moving block 3. When an object to be hoisted needs to be hoisted, the linear actuator 2 is first started and drives the lead screw to rotate. When the lead screw rotates, it drives the moving block 3 to move along the top of the housing 1. Then, the wire rope crane 5 is started and drives the hook 4 to descend through the wire rope until the hook 4 and the object to be hoisted are hoisted. After this, the wire rope crane 5 is started and drives the hook 4 to rise through the wire rope. When the wire rope crane 5 is started, the displacement block 62 can slide back and forth along the mounting plate 61. During the sliding process, the lubrication block 63 intermittently contacts the wire rope, achieving intermittent contact lubrication of the wire rope and improving the service life of the wire rope.

[0029] See Figures 2-4 As shown, the lubrication mechanism 6 also includes a mounting plate 64, a rotating rod 65, and a transmission belt 66; the mounting plate 64 is installed beside the mounting plate 61 and is located above the housing 1; the rotating rod 65 is rotatably installed beside the mounting plate 64 and is located beside the mounting plate 61; the transmission belt 66 is installed beside the linear actuator 2, one end of the transmission belt 66 is connected to the output end of the linear actuator 2, and the other end of the transmission belt 66 is connected to the rotating rod 65.

[0030] When the steel rope crane 5 starts, it can drive the rotating rod 65 to rotate synchronously through the transmission belt 66.

[0031] See Figures 3-5 As shown, the lubrication mechanism 6 also includes a connecting rod 67; the connecting rod 67 is rotatably disposed outside the rotating rod 65, one end of the connecting rod 67 is rotatably connected to the rotating rod 65, and the other end of the connecting rod 67 is rotatably connected to the displacement block 62.

[0032] When the rotating rod 65 rotates, it can drive the displacement block 62 to slide back and forth along the stroke groove opened on the top of the mounting plate 61 through the rotating connecting rod 67. When the displacement block 62 slides, it can drive the lubrication block 63 to contact the steel rope, so as to achieve intermittent contact lubrication of the steel rope.

[0033] See Figure 4 and Figure 5 As shown, the lubrication mechanism 6 also includes fasteners 68; the top of the displacement block 62 has an opening for the lubrication block 63 to be inserted; the fasteners 68 are a pair and are respectively rotatably disposed on both sides of the displacement block 62, and the fasteners 68 can screw the lubrication block 63 against the top of the displacement block 62 by means of thread.

[0034] When installing the lubricating block 63, first rotate the pair of fasteners 68 in the opposite direction until the fasteners 68 disengage from the outside of the displacement block 62. Then place the lubricating block 63 into the opening at the top of the displacement block 62, and then rotate the fasteners 68 until the fasteners 68 abut the lubricating block 63 against the top of the displacement block 62. This allows for quick installation and removal of the lubricating block 63.

[0035] See Figure 5 As shown, the lubrication mechanism 6 also includes a positioning plate 69 and a lubrication box 691; the positioning plate 69 is disposed on the top of the mounting plate 61 and is located beside the displacement block 62; the lubrication box 691 is disposed on the bottom of the positioning plate 69 and is located above the lubrication block 63.

[0036] The lubrication tank 691 has an opening at the bottom for lubricating oil to drain, and a solenoid valve is installed inside the lubrication tank 691 to control the lubricating oil discharge. When it is necessary to replenish lubrication to the lubrication block 63, the solenoid valve is activated, allowing the lubricating oil inside the lubrication tank 691 to drain through the opening at the bottom and lubricate the lubrication block 63.

[0037] See Figure 5 As shown, the lubricating block 63 is rectangular in shape and is made of sponge material.

[0038] To reduce production costs, the lubricating block 63 is preferably made of sponge. Sponge has excellent oil absorption properties and can effectively absorb lubricating oil. At the same time, when the sponge lubricating block 63 comes into contact with the steel rope, it can undergo compression deformation, thereby allowing the lubricating oil to adhere evenly to the outside of the steel rope.

[0039] See Figure 6 As shown, the abutting mechanism 7 includes a hydraulic cylinder 71 and an ejector block 72; the hydraulic cylinder 71 has a pair and is respectively disposed on the side of a pair of moving blocks 3; the ejector block 72 has a pair and is respectively disposed at the output end of the hydraulic cylinder 71.

[0040] When stabilizing the hook 4 and steel rope during the lifting or lowering process is required, the hydraulic cylinder 71 is first activated to drive the ejector block 72 to move. After the ejector block 72 moves to contact the steel rope, it can limit the sway range of the steel rope, thereby reducing the sway of the hook 4 and improving the lifting stability of the steel rope and hook 4.

[0041] See Figure 6 As shown, the top of the ejector block 72 has an opening for the steel rope to pass through.

[0042] The opening at the top of the ejector block 72 allows for a smaller range of sway in the steel rope. This indirectly reduces the amplitude of the rope's sway, helping to improve the stability of the lifting process.

[0043] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
