Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a switch structure for a suspended monorail. Background Art

[0002] Suspended monorails are vehicles suspended beneath tracks, suitable for use in small and medium-sized cities. By moving ground traffic into the air, they alleviate urban transportation challenges without requiring the expansion of existing road infrastructure. They overcome the shortcomings of other rail transit systems and offer significant advantages in construction and operation.

[0003] The Chinese utility model with authorization announcement number CN207828713U discloses a suspended monorail turnout compensating rail lifting device. When in use, the device drives the left and right sliders to slide respectively through a driving mechanism, so that the upper slider can be lifted up and down, driving the compensating rail to be lifted and lowered in situ, avoiding the large-scale translation of the compensating rail in the traditional turnout structure, greatly reducing the activity space of the compensating rail, so that the turnout width can be further reduced. However, the device has certain defects in actual use. The left and right sliders on the device slide by contact with the base. Since the contact surface between the slider and the base may be uneven or have impurities, the slider may become stuck or blocked during the sliding process, affecting the lifting and lowering stability of the compensating rail. Therefore, it is necessary to redesign a turnout structure for a suspended monorail to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a switch structure for a suspended monorail.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The cam is provided with a plurality of pulleys, each of which is connected to the left and right sliding blocks, and the upper end surfaces of the left and right sliding blocks are inclined, and the inclined surfaces are rotatably connected to pulleys 2. The upper end surface of the base is fixedly connected to two groups of sleeves, and the upper end surfaces of the two groups of sleeves are open. Connecting rods are slidably connected to the sleeves, and the ends of the connecting rods are fixedly connected to compensating rails. The outer walls on both sides of the compensating rails are inclined, matching the inclined surfaces of the left slider and the outer wall of the slide rails. The provided pulley 2 contacts the outer wall of the compensation rail, and the outer wall of the base is installed with a sliding mechanism that enables the left slider and the slide rail to slide.

[0007] Preferably, the sliding mechanism comprises a double-headed threaded rod rotatably connected to the outer wall of the base, and the double-headed threaded rod is threadedly connected to both the left slider and the right slider (4).

[0008] Preferably, outer walls on both sides of the plurality of pulleys are in contact with inner walls on both sides of the slide rails, and both ends of the double-headed threaded rod are fixedly connected with a driving gear and a limit block respectively.

[0009] Preferably, a moving block is slidably connected in the sleeve, and the connecting rod is fixedly connected to the upper end surface of the moving block.

[0010] Preferably, a spring is fixedly connected to the inner bottom of the sleeve, and the other end of the spring is fixedly connected to the moving block.

[0011] Preferably, a limiting ring is fixedly connected to the mouth of the sleeve, and the radius of the limiting ring is smaller than the radius of the moving block.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model significantly reduces the friction between the left and right sliders and the base when they are in direct contact and sliding by setting pulleys 1 and 2. This design effectively solves the jamming and blocking phenomena that may occur when the sliders are in direct contact with the base in traditional turnout structures, greatly improves operational efficiency and reliability, makes the compensation rail more accurate and stable during the lifting process, and ensures high precision and high reliability of turnout switching.

[0014] 2. The utility model can precisely control the sliding stroke of the slider by rotating the drive gear, ensuring that the left and right sliders slide synchronously toward or relative to each other in a horizontal state. At the same time, the spring provides an upward elastic buffer when the compensation rail descends, preventing malfunctions caused by external impact and improving the safety of the device.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3 A turnout structure for a suspended monorail includes a base 1, with two sets of slide rails 3 provided on the upper end of the base 1. The two sets of slide rails 3 are symmetrically positioned and are slidably connected to multiple sets of pulleys 5 inside. The multiple sets of pulleys 5 are connected to a left slider 2 and a right slider 4 in pairs. The upper end surfaces of the left slider 2 and the right slider 4 are both inclined, and the inclined surfaces are rotatably connected to pulleys 11. The upper end surface of the base 1 is fixedly connected to two sets of sleeves 6. The upper end surfaces of the two sets of sleeves 6 are both open. A connecting rod 13 is slidably connected to the sleeve 6, and the end of the connecting rod 13 is fixed. It is connected to a compensation rail 7, and the outer walls on both sides of the compensation rail 7 are inclined, matching the inclined surfaces of the outer walls of the left slider 2 and the slide rail 3. The provided pulley 2 11 contacts the outer wall of the compensation rail 7, and the outer wall of the base 1 is installed with a sliding mechanism that enables the left slider 2 and the slide rail 3 to slide; the pulley 1 5 slides smoothly in the slide rail 3, reducing the friction with the left slider 2 and the right slider 4, and improving the operating efficiency. The pulley 2 11 contacts the inclined surface of the compensation rail 7, reducing direct friction, and the inclined surface design of the compensation rail 7 matches the inclined surfaces of the left slider 2 and the right slider 4, ensuring the accuracy of the movement process.

[0021] The sliding mechanism includes a double-threaded rod 8 rotatably connected to the outer wall of the base 1, the double-threaded rod 8 is threadedly connected to the left slider 2 and the right slider (4), the outer walls of the multiple sets of pulleys 5 on both sides are in contact with the inner walls of the slide rail 3 on both sides, and the two ends of the double-threaded rod 8 are fixedly connected to a driving gear 9 and a limit block 12 respectively; when the double-threaded rod 8 drives the left slider 2 and the right slider 4 to slide, the pulley 5 is limited in the slide rail 3, so that the sliding direction of the left slider 2 and the right slider 4 is horizontal.

[0022] A moving block 14 is slidably connected inside the sleeve 6, and the connecting rod 13 is fixedly connected to the upper end surface of the moving block 14. A spring 10 is fixedly connected to the bottom of the sleeve 6, and the other end of the spring 10 is fixedly connected to the moving block 14. A limiting ring 15 is fixedly connected to the mouth of the sleeve 6, and the radius of the limiting ring 15 is smaller than the radius of the moving block 14; the limiting ring 15 controls the maximum rising height of the moving block 14 to prevent the connecting rod 13 from extending excessively and causing equipment failure.

[0023] In the present invention, the specific function of the device is as follows: in the initial state, pulleys 1 5 are connected to the left slider 2 and the right slider 4 in pairs, so that the two can slide smoothly in the slide rail 3 to reduce friction. At the same time, pulley 2 11 contacts the inclined surface of the compensation rail 7 to reduce friction and ensure accurate movement. When the double-headed threaded rod 8 rotates through the driving gear 9, it drives the left slider 2 and the right slider 4 to slide horizontally. The outer walls of the pulleys 1 5 on both sides of the slide rail 3 contact the inner wall of the slide rail 3, limiting the left slider 2 and the right slider 4 to slide only in a horizontal state, ensuring a smooth sliding process.

[0024] When the double-headed threaded rod 8 rotates forward, the left slider 2 and the right slider 4 slide toward each other, thereby driving the compensation rail 7 to slide upward. Conversely, when the double-headed threaded rod 8 rotates in the opposite direction, the left slider 2 and the right slider 4 slide relative to each other, and the compensation rail 7 resets downward.

[0025] The spring 10 provides an upward elastic force, providing cushioning and support when the compensation rail 7 descends, avoiding failures caused by external force impact. In addition, the limit ring 15 limits the maximum rising height of the moving block 14, ensuring that the connecting rod 13 and the compensation rail 7 will not be damaged due to excessive rising.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
