Description

Technical Field

[0001] The invention belongs to the technical field of crossbeam clamping parking mechanisms of mechanical equipment, and in particular relates to a crossbeam clamping parking mechanism and a use method thereof. Background Art

[0002] The braking of the existing crossbeam running rail trolley is provided by a transmission mechanism, and the parking force is also provided by the transmission mechanism. It is used to operate in the vertical direction of the trolley. When the trolley needs a large horizontal force during operation, the transmission mechanism is not enough to keep the trolley in a prohibited state. The trolley will rely on its own movement to eliminate the horizontal force transmitted by the operation, resulting in the operation cannot be completed normally, and mobile fixed-point operation cannot be achieved. The movement of the operation will lead to the safe use of the equipment, unstable operation, and no safety guarantee.

[0003] CN107399310B provides a parking mechanism and automobile, including a base, a drive motor, a rotating part, two connecting rods, and two sliding rods. The driving motor drives the rotating part to rotate, and the rotating part drives the sliding rods through the connecting rods, so that the sliding rods move toward or in opposite directions along the guide rails, converting the rotational motion of the driving motor into linear motion of the sliding rods, so that the brakes are locked or unlocked by a parking brake cable fixedly connected to the sliding rods, thereby realizing the parking function. The parking mechanism of the present invention has a simple structure, low cost, small layout space, and is easy to operate, which can realize lightweight and intelligent automobile operation. However, it is in the automotive field and is not suitable for the present invention, and the parking is unstable. Summary of the Invention

[0004] In order to overcome the problem that the horizontal parking force of the existing rail pulley is insufficient, resulting in instability, unreliability and unsafeness during operation, the present invention provides a beam-type clamping parking mechanism and a method of use. The beam-type clamping parking mechanism is used for parking the rail trolley during the parking operation of the beam, preventing the rail trolley from moving back and forth due to excessive horizontal force during operation, which affects the reliability, safety and accuracy of the operation position.

[0005] The technical solution adopted in the present invention is:

[0006] A crossbeam type clamping parking mechanism includes an upper crossbeam, a lower crossbeam and a mounting seat. The upper crossbeam is arranged parallel to the lower crossbeam and is connected to the lower crossbeam via a plurality of mounting seats. An oil cylinder is provided in each mounting seat. The upper and lower ends of the oil cylinder are respectively connected to the upper crossbeam and the lower crossbeam via corresponding elastic components.

[0007] Upper friction blocks are provided on the lower end surfaces of both ends of the upper crossbeam; lower friction blocks are provided on the upper end surfaces of both ends of the lower crossbeam.

[0008] The oil cylinder comprises an oil cylinder barrel and an oil cylinder rod; the elastic component comprises an upper elastic component and a lower elastic component; the end of the oil cylinder barrel is connected to the upper elastic component, and the end of the oil cylinder rod is connected to the lower elastic component.

[0009] The mounting seat comprises a mounting plate and a guide sleeve. The mounting plate is two vertical plates, and the guide sleeve is fixed between the two mounting plates through a horizontal connecting plate.

[0010] The guide sleeve is in the shape of a cylinder with upper and lower openings, and the oil cylinder barrel of the oil cylinder is arranged in the guide sleeve.

[0011] The length of the guide sleeve is smaller than that of the mounting plate, and a circular hole is provided in the middle of the mounting plate.

[0012] The upper end of the upper elastic component is connected to the upper crossbeam through an upper fastening nut; the lower end of the lower elastic component is connected to the lower crossbeam through a lower fastening nut.

[0013] A method for using a crossbeam-type clamping parking mechanism comprises the following specific steps: the crossbeam-type clamping parking mechanism is installed on a track pulley, and the cylinder end is mounted on a mounting seat through an upper elastic component, an upper crossbeam, and an upper fastening nut; after oil is passed through the cylinder end, the cylinder rod is extended, thereby increasing the distance between the upper crossbeam and the lower crossbeam, the upper elastic component and the lower elastic component are in a state of minimum elastic force, the upper friction block and the lower friction block do not contact the track beam and a gap is left, and the crossbeam-type clamping parking mechanism is in a follow-up non-braking state;

[0014] When the rail pulley moves to the specified position, oil is supplied to the end of the cylinder rod, the cylinder rod retracts and drives the upper elastic component and the lower elastic component to compress, so that the distance between the upper crossbeam and the lower crossbeam is shortened, the upper friction block and the lower friction block contact and lock the guide rail, and the crossbeam clamping parking mechanism is in the parking state;

[0015] The rail pulley carries equipment for operation. After the operation is completed, oil is passed through the end of the cylinder barrel, the cylinder rod extends, the upper elastic component and the lower elastic component are reset from the compressed state, the distance between the upper beam and the lower beam increases, the upper friction block and the lower friction block are separated from the track, and the parking is released.

[0016] The crossbeam type clamping parking mechanism is connected and fixed to the rail pulley through the mounting plate of the mounting seat.

[0017] Beneficial effects of the present invention:

[0018] The present invention provides a cross-beam clamping parking mechanism, which is installed on a rail pulley and moves with the trolley. When the pulley is parked, the cross-beam clamping parking mechanism locks the rails on both sides through hydraulic pressure, so that the pulley has sufficiently large friction in the horizontal direction, so that the horizontal force generated during operation is completely eliminated by the cross-beam clamping parking mechanism. The cross-beam clamping parking mechanism can also be used as an emergency brake for the rail pulley.

[0019] In this invention, an oil cylinder controls the extension and retraction of the upper and lower elastic components, thereby controlling the spacing between the upper and lower crossbeams. The oil cylinder acts on the elastic components, closing the gap between the upper and lower crossbeams. The upper and lower friction blocks contact the rails of the track pulley and lock the guide rails, placing the crossbeam clamping parking mechanism in the parked position. Similarly, the oil cylinder increases the gap between the upper and lower crossbeams, separating the upper and lower friction blocks from the rails and releasing the parking mechanism.

[0020] The present invention provides a beam-type clamping parking mechanism, which enables the rail pulley to have an independent parking function during parking operations. The parking function withstands the horizontal constant force and horizontal impact force generated during the operation, ensuring the stability and safety of the operation, allowing the actuator to complete the operation accurately and smoothly, thereby improving the stability of the equipment structure, the safety of equipment operation, and the improvement of operation quality and efficiency.

[0021] The use of the present invention solves the problem of the stability of the rail pulley during parking operations, so that the pulley always remains stationary during operation, the operation can be completed smoothly at a fixed point, and the safety of the operation is guaranteed. When the pulley cannot stop normally, this parking mechanism can also be used to force the pulley to stop immediately and cannot move to ensure the safety of the overall operation.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] Example 1:

[0035] In order to overcome the problem that the existing rail pulley has insufficient horizontal parking force, which leads to instability, unreliability and unsafe operation, the present invention provides a Figure 1-6 A beam-type clamping parking mechanism and a method of use are shown. The beam-type clamping parking mechanism is used for parking a beam-operated rail trolley during parking operations to prevent the rail trolley from moving back and forth due to excessive horizontal force during operation, affecting the reliability, safety and accuracy of the operation position.

[0036] A crossbeam type clamping parking mechanism includes an upper crossbeam 1, a lower crossbeam 2 and a mounting seat 5. The upper crossbeam 1 and the lower crossbeam 2 are arranged in parallel. The upper crossbeam 1 and the lower crossbeam 2 are connected by multiple mounting seats 5. Each mounting seat 5 is provided with an oil cylinder. The upper and lower ends of the oil cylinder are respectively connected to the upper crossbeam 1 and the lower crossbeam 2 through corresponding elastic components.

[0037] The present invention provides a cross-beam clamping parking mechanism, which is installed on a rail pulley and moves with the trolley. When the pulley on the rail pulley needs to be parked, the cross-beam clamping parking mechanism locks the two side rails on the rail pulley through the hydraulic control of the oil cylinder, so that the pulley has a sufficiently large friction force in the horizontal direction, so that the horizontal force generated during operation is completely eliminated by the cross-beam clamping parking mechanism. At the same time, the cross-beam clamping parking mechanism provided by the present invention can also be used as an emergency brake for the rail pulley.

[0038] In the present invention, Figure 5 and Figure 6As shown, the hydraulic cylinder controls the extension and retraction of the upper and lower elastic components, thereby controlling the spacing between the upper and lower crossbeams. The hydraulic cylinder acts on the elastic components, closing the gap between the upper and lower crossbeams. The upper and lower friction blocks contact the rails of the track pulley and lock the guide rails, placing the crossbeam clamping parking mechanism in the parked position. Similarly, the hydraulic cylinder increases the gap between the upper and lower crossbeams, separating the upper and lower friction blocks from the rails and releasing the parking mechanism.

[0039] The use of the present invention solves the problem of the stability of the rail pulley during parking operations, so that the pulley always remains stationary during operation, the operation can be completed smoothly at a fixed point, and the safety of the operation is guaranteed. When the pulley cannot stop normally, this parking mechanism can also be used to force the pulley to stop immediately and cannot move to ensure the safety of the overall operation.

[0040] In the case where the length of the upper crossbeam 1 and the lower crossbeam 2 is relatively small, it is preferred that there be only one mounting base 5 to avoid waste. The oil cylinder in the mounting base 5 can also be replaced by an air cylinder, as long as the parking effect is good.

[0041] Example 2:

[0042] Based on Example 1, in this embodiment, preferably, upper friction blocks 3 are provided on the lower end surfaces of both ends of the upper crossbeam 1; lower friction blocks 4 are provided on the upper end surfaces of both ends of the lower crossbeam 2.

[0043] In the present invention, Figure 1 As shown, a plurality of round through holes are provided on the upper crossbeam 1 and the lower crossbeam 2. A plurality of stiffening plates are provided on each of the upper crossbeam 1 and the lower crossbeam 2 to ensure that the strength of the upper crossbeam 1 and the lower crossbeam 2 is sufficient, so that the parking operation can be effectively performed.

[0044] In the present invention, Figure 1 and Figure 2 As shown, the length of the upper crossbeam 1 is the same as that of the lower crossbeam 2. The lower crossbeam 2 comprises a horizontal section, a connecting section, and a friction section. Both ends of the horizontal section are connected to the friction section via the connecting section. The lower friction block 4 is positioned on the friction section, forming an angle between the friction section and the connecting section to ensure that the distance from the upper crossbeam 1 to the friction section is greater than the distance from the upper crossbeam 1 to the horizontal section. The friction section and the upper crossbeam 1 remain parallel. The positions of the upper friction blocks 3 and lower friction blocks 4 correspond one-to-one, ensuring that when the hydraulic cylinder is activated, the upper and lower friction blocks 3 and 4 lock onto the corresponding rails even if the distance between the upper and lower crossbeams 1 and 2 changes, thereby enabling parking and release operations.

[0045] Preferably, the oil cylinder includes a cylinder barrel 6 and a cylinder rod 10; the elastic component includes an upper elastic component 8 and a lower elastic component 9; the end of the oil cylinder barrel 6 is connected to the upper elastic component 8, and the end of the oil cylinder rod 10 is connected to the lower elastic component 9.

[0046] Preferably, the upper end of the upper elastic component 8 is connected to the upper beam 1 through an upper fastening nut 7; the lower end of the lower elastic component 9 is connected to the lower beam 2 through a lower fastening nut 11.

[0047] In the present invention, the upper elastic component 8 and the lower elastic component 9 have the same structure. In this embodiment, the elastic component is preferably a spring, and it is sufficient to ensure that it has good stretching and retraction effects.

[0048] Preferably, the mounting seat 5 includes a mounting plate 5-1 and a guide sleeve 5-2, the mounting plate 5-1 is two vertical plates, and the guide sleeve 5-2 is fixed between the two mounting plates 5-1 through a horizontal connecting plate.

[0049] Preferably, the guide sleeve 5-2 is cylindrical with openings at the top and bottom, and the cylinder barrel 6 of the oil cylinder is arranged in the guide sleeve 5-2.

[0050] Preferably, the length of the guide sleeve 5-2 is smaller than the length of the mounting plate 5-1, and a circular hole is opened in the middle of the mounting plate 5-1.

[0051] In the present invention, the length of the guide sleeve 5-2 is determined according to the size of the oil cylinder, and it is sufficient to ensure that the oil cylinder has a fixing and guiding effect. Figure 3 and 4 As shown, a circular hole is opened in the middle of the mounting plate 5-1, and mounting holes are provided around the circular hole. Rectangular grooves are opened at the upper and lower ends of the inner sides of the two mounting plates 5-1; the mounting plates 5-1 are used to connect and fix with the rail pulley.

[0052] In the present invention, the guide sleeve 5-2 acts on the guide to ensure that its force acts vertically on the corresponding elastic component when the cylinder moves. Multiple cylinders are linked at the same time to adjust the distance between the upper beam 1 and the lower beam 2, ensuring that the upper beam 1 and the lower beam 2 can lock the track through the upper and lower friction blocks at the required distance.

[0053] Example 3:

[0054] Based on the embodiment 1 or 2, this embodiment provides a method for using a cross-beam clamping parking mechanism, which specifically comprises the following steps: the cross-beam clamping parking mechanism is installed on the rail pulley, and the end of the cylinder 6 is mounted on the mounting seat 5 through the upper elastic component 8, the upper crossbeam 1 and the upper fastening nut 7; after oil is passed through the end of the cylinder 6, the cylinder rod 10 is extended, so that the distance between the upper crossbeam 1 and the lower crossbeam 2 is increased, the upper elastic component 8 and the lower elastic component 9 are in the minimum elastic force state, the upper friction block 3 and the lower friction block 4 do not contact the rail beam and a gap is left, and the cross-beam clamping parking mechanism is in a follow-up non-braking state;

[0055] When the rail pulley moves to the specified position, oil is passed through the end of the cylinder rod 10, the cylinder rod 10 retracts and drives the upper elastic component 8 and the lower elastic component 9 to compress, so that the distance between the upper crossbeam 1 and the lower crossbeam 2 is shortened, the upper friction block 3 and the lower friction block 4 contact with the guide rail and lock the guide rail, and the crossbeam type clamping parking mechanism is in the parking state; Figure 6 shown.

[0056] The rail pulley carries the equipment for operation. After the operation is completed, the oil is passed through the end of the cylinder barrel 6, the cylinder rod 10 extends, the upper elastic component 8 and the lower elastic component 9 are reset from the compressed state, the distance between the upper crossbeam 1 and the lower crossbeam 2 increases, the upper friction block 3 and the lower friction block 4 are separated from the track, and the parking is released. Figure 5 shown.

[0057] The crossbeam type clamping parking mechanism is connected and fixed to the rail pulley via the mounting plate 5 - 1 of the mounting seat 5 .

[0058] The present invention provides a beam-type clamping parking mechanism, which enables the rail pulley to have an independent parking function during parking operations. The parking function withstands the horizontal constant force and horizontal impact force generated during the operation, ensuring the stability and safety of the operation, allowing the actuator to complete the operation accurately and smoothly, thereby improving the stability of the equipment structure, the safety of equipment operation, and the improvement of operation quality and efficiency.

[0059] The present invention provides a cross-beam clamping parking mechanism, which is installed on a rail pulley and moves with the trolley. When the pulley is parked, the cross-beam clamping parking mechanism locks the rails on both sides through hydraulic pressure, so that the pulley has sufficiently large friction in the horizontal direction, so that the horizontal force generated during operation is completely eliminated by the cross-beam clamping parking mechanism. The cross-beam clamping parking mechanism can also be used as an emergency brake for the rail pulley.

[0060] The use of the present invention solves the problem of the stability of the rail pulley during parking operations, so that the pulley always remains stationary during operation, the operation can be completed smoothly at a fixed point, and the safety of the operation is guaranteed. When the pulley cannot stop normally, this parking mechanism can also be used to force the pulley to stop immediately and cannot move to ensure the safety of the overall operation.

[0061] Since the crossbeam-type clamping parking mechanism provided by the present invention is adopted on the rail pulley, the rail pulley has an independent parking function during parking operation. The parking function bears the horizontal constant force and horizontal impact force generated during operation, thereby ensuring the stability and safety of the operation, allowing the actuator to complete the operation accurately and smoothly, improving the stability of the equipment structure, the safety of equipment operation, and the improvement of operation quality and efficiency.
