Description

Technical Field

[0001] The present invention relates to the technical field of lifting and transversely moving parking equipment, and in particular to a rope checking device, a use method and parking equipment. Background Art

[0002] The lifting and transverse moving parking equipment currently on the market needs to control the rising and falling processes of the vehicle plate and stop in place during operation. At the same time, it is also necessary to detect whether all chains or all steel ropes are loose. For multi-layer lifting and transverse moving products lifted by steel ropes, it is necessary to have the function of detecting the looseness of four steel ropes.

[0003] Most of the multi-layer lifting and transverse sliding products are lifted by wire ropes, and the stop is controlled by touching the switch when the carrier plate is lowered into place. This switch is usually set on the ground, but the carrier plate will be affected by external forces such as wind during the descent process, which is prone to shaking, resulting in problems such as the switch not being able to be hit after the plate is lowered or directly hitting the switch. In addition, the switch is easily damaged by being stepped on, causing switch failure.

[0004] Even if the switch is arranged on the transverse frame, especially for the transverse frame with a double-row rope structure, as the height of the multi-layer lifting and transverse moving equipment increases, the angle of the wire rope becomes larger, which makes it very difficult to detect the status of the two wire ropes at the same time. The larger the angle, the greater the lateral force on the rope detection device. Therefore, in actual use, the rope detection device is often damaged.

[0005] Furthermore, due to the heavy weight of the wire rope and the distributed control of the overall equipment, the rope inspection device at the high-rise level needs to travel about twice as long as that at the low-rise level, and the rope inspection device needs to be designed according to the high-rise level travel. Therefore, how to design a rope inspection device that not only meets the functional requirements, but also does not occupy parking space, and can make the structure simple and easy to install is a difficult problem.

DETAILED DESCRIPTION

[0038] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0041] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application after combining the specific content of the technical solution.

[0042] Reference Figures 1 to 6 The rope checking device of the first aspect of the present application is applied to a lifting and transverse moving parking device in which a drum cooperates with a wire rope to lift and lower, and particularly relates to a device for detecting in-place, limit, loose and broken ropes. The rope checking device includes at least two rear rope checking components 32 and at least two front rope checking components 31.

[0043] The rear rope-detecting component 32 is used to detect the rope being in position and the rope being loose or broken, and the front rope-detecting component 31 includes a first transmission component, a first bracket 2, a first guide wheel 1, a first elastic member 8, a first switch 15 and a second switch 16. The first guide wheel 1 is rotatably arranged on the first bracket 2, the first transmission component is fixedly connected to the first bracket 2, the first switch 15 and the second switch 16 are spaced apart up and down, the first switch 15 is used to detect the rope being loose or broken, and the second switch 16 is used to detect the extreme position; and the first elastic member 8 acts on the first transmission component to make the first transmission component have a tendency to move downward, and the first bracket 2 is suitable for triggering the first switch 15 when it moves downward to the first preset position, and is suitable for triggering the second switch 16 when the first bracket 2 moves downward to the second preset position.

[0044] It should be noted that since the position of the rear end traction rope 30 is fixed, there is no angle change, and detection is convenient, there are many ways to detect its arrival and broken rope in conventional existing technologies, such as obtaining the arrival stop information by touching a switch to realize arrival status detection, and detecting the tension of the rear end traction rope 30, the hanging range and position of the rear end traction rope 30, etc., which can realize the loose and broken rope detection. The specific application of conventional existing technologies will not be further described here.

[0045] It should be noted that the front-end traction rope 29 and the rear-end traction rope 30 are steel wire ropes at corresponding positions in specific application scenarios. Based on the fixed connection between the first bracket 2 and the first transmission member, the first elastic member 8 acts on the first transmission member to make the first transmission member tend to move downward. The first guide wheel 1 is suitable for the front-end traction rope 29 to pass through and around. Therefore, the front-end traction rope 29 has an upward force on the first bracket 2. Under normal conditions, the force of the front-end traction rope 29 and the first elastic member 8 combined with the first bracket 2 is dynamically balanced. If the front-end traction rope 29 becomes loose, broken or in other unexpected conditions, the first elastic member 8 will drive the first bracket 2 to move downward, and can trigger the first switch 15 and the second switch 16 in sequence according to the severity of different faults, thereby realizing the specific situation detection of the front-end traction rope 29.

[0046] Reference Figures 1 to 6 The rope checking device of the first aspect embodiment of the present application is specifically installed on the longitudinal beam 12 of the parking space. It has a reliable structure and is easy to install, and can avoid accidental human damage. The position of the rear end traction rope 30 detected by the rear rope checking component 32 is fixed, without angle change, and detection is convenient. The front end traction rope 29 detected by the front rope checking component 31 will swing and change angle. Therefore, the detection of the two steel ropes is separated, so that the front rope checking component 31 and the rear rope checking component 32 can simultaneously meet the travel required by the high-rise lifting and transverse movement equipment. The two components can be used in combination to stably and reliably realize the detection functions of the vehicle loading plate 28 being in place, the lower limit position and the loose rope situation.

[0047] In some embodiments of the present application, specific reference is made to Figure 3 and Figure 5 The first transmission assembly includes a circular structure 3, a first guide member and a second guide member. The front rope checking component 31 also includes a front rope checking bracket 7. The first guide member and the second guide member are arranged on the front rope checking bracket 7 at intervals along the longitudinal direction, and the first guide member can slide laterally. The circular structure 3 can be rotatably arranged in the circumferential direction through the first guide member and the second guide member. The circular structure 3 is fixedly connected to the first bracket 2, and the first elastic member 8 acts on the circular structure 3.

[0048] It is understandable that the circular structure 3 can be a round steel or other columnar structure, and the first elastic member 8 is a spring. Since the front suspension point wire rope will change angle with the rotation of the drum to produce a displacement difference, the first guide is designed to be a slidable structure, and the slidable first guide can slide along with the angle change of the wire rope. Since the circular structure 3 itself can rotate, it also satisfies the angle change of the wire rope. At the same time, the setting of the first guide and the second guide can ensure the smooth sliding of the circular structure 3. The first guide and the second guide are preferably made of nylon material so that no noise is generated during the movement.

[0049] In some embodiments of the present application, specific reference is made to Figure 3 and Figure 5 The first guide member includes two front upper guide wheels 4, the second guide member includes two front lower guide wheels 6, and the front rope checking component 31 also includes a first hitting rod 9 and a sleeve 5; the front lower guide wheel 6 is rotatably fixed on the front rope checking bracket 7, the sleeve 5 is axially slidably set on the front rope checking bracket 7, and the front upper guide wheel 4 is rotatably set through the sleeve 5, and the circular structure 3 is penetrated between the two front upper guide wheels 4 and between the two front lower guide wheels 6; the first hitting rod 9 is arranged at the top end of the first bracket 2 and is suitable for cooperating with the first switch 15 and the second switch 16, the bottom end of the first bracket 2 is fixedly connected to the top end of the circular structure 3, the bottom end of the circular structure 3 is penetrated in the front rope checking bracket 7, one end of the first elastic member 8 abuts against the front rope checking bracket 7, and the first elastic member 8 is sleeved on the bottom end of the circular structure 3.

[0050] It can be understood that the two front upper guide wheels 4 and the two front lower guide wheels 6 are fixed to the front rope inspection bracket 7 in a detachable manner, wherein the front lower guide wheel 6 is fixed with a sleeve 5 or a rotating shaft, and the front upper guide wheel 4 can slide axially with the sleeve 5. After the round steel is connected to the first bracket 2, it passes through the circular hole formed by the two front upper guide wheels 4 and the two front lower guide wheels 6, and then the first guide wheel 1 and the first driving rod 9 are installed on the first bracket 2. The spring is inserted into the bottom of the round steel and locked with a nut to make the spring in a compressed state. A rectangular hole is opened above the longitudinal beam 12 of the parking space, and multiple circular holes are opened on the inner side surface to insert the front bracket 13. There are multiple threaded holes on the front bracket 13, so the front rope inspection bracket 7 can be fixed to the front bracket 13 with screws. The upper end of the front bracket 13 is connected to the front switch bracket 14, and two switches are installed on the front switch bracket 14 for detecting the loose rope (the first switch 15 at the upper part) and the limit (the second switch 16 at the lower part).

[0051] In some embodiments of the present application, the front rope checking component 31 further includes a wheelbase adjustment block 11, which is disposed on the front rope checking bracket 7 and is used to adjust the distance between the two front upper guide wheels 4. More specifically, the wheelbase adjustment block 11 is adjustably disposed on the front rope checking bracket 7 by bolts, thereby adjusting the distance between the front upper guide wheels 4.

[0052] In some embodiments of the present application, the first guide member also includes a first connecting plate 10, and the second guide member also includes a second connecting plate. The front upper guide wheel 4 and the front lower guide wheel 6 are both provided with a first groove for limiting the circular structure 3. The first connecting plate 10 is arranged on the outer side of the two front upper guide wheels 4 and forms a first space suitable for limiting the circular structure 3 with the front rope checking bracket 7. The second connecting plate is arranged on the outer side of the two front lower guide wheels 6 and forms a second space suitable for limiting the circular structure 3 with the front rope checking bracket 7.

[0053] It can be understood that the first guide wheel 1 of the device presses the front suspension point wire rope, the slidable front upper guide wheel 4 can slide on the shaft sleeve following the angle change of the wire rope, and the circular structure 3 itself can also rotate, so the first space and the second space can both provide the circular structure 3 with the angle change of the wire rope. Since the front lower guide wheel 6 is rotatably fixed, the second space can be smaller than the first space. In other embodiments, the first connecting plate 10 and the second connecting plate can be adjusted in a detachable manner, so the setting position of the first connecting plate 10 and the second connecting plate can be adjusted according to actual conditions, thereby adjusting the size of the first space and the second space. Specifically, the first groove is set as a semicircular arc groove to ensure the smooth sliding of the circular structure 3, and the nylon material can prevent noise from being generated during the movement.

[0054] In some embodiments of the present application, specific reference is made to Figure 6 The rear rope checking component 32 includes a second transmission assembly, a second bracket 21, a second guide wheel 18, a second elastic member 24, a third switch and a fourth switch. The third switch and the fourth switch are arranged at intervals up and down. The third switch is used to detect the position of the rear end traction rope 30, and the fourth switch is used to detect the loosening of the rear end traction rope 30. The second guide wheel 18 is suitable for the rear end traction rope 30 to pass through and around. The second guide wheel 18 is rotatably arranged on the second bracket 21. The second transmission assembly is fixedly connected to the second bracket 21. The second elastic member 24 acts on the second transmission assembly so that the second transmission assembly has a tendency to move downward. When the second bracket 21 moves downward to the third preset position, it is suitable for triggering the third switch. When the second bracket 21 moves downward to the fourth preset position, it is suitable for triggering the fourth switch.

[0055] It can be understood that since the position of the wire rope at the rear suspension point is fixed and there is no angle change, the movement direction of the second transmission component is also relatively determined to be the vertical direction. Based on the fixed connection between the second bracket 21 and the second transmission member, the second elastic member 24 acts on the second transmission member to make the second movable member have a tendency to move downward. The second guide wheel 18 is suitable for the rear end traction rope 30 to pass through and around, so the rear end traction rope 30 has an upward force on the second bracket 21. Under normal conditions, the force of the rear end traction rope 30 and the second elastic member 24 combined with the second bracket 21 is dynamically balanced. If the rear end traction rope 30 becomes loose, broken or other unexpected conditions occur, the second elastic member 24 will drive the second bracket 21 to move downward, and can trigger the third switch and the fourth switch in sequence according to the severity of different faults, thereby realizing the specific situation detection of the wire rope at the rear suspension point.

[0056] In some embodiments of the present application, specific reference is made to Figure 4 and Figure 6The second transmission assembly includes a square structure 20, a third connecting plate 23 and two rear guide wheels 25. The rear rope checking component 32 also includes a rear rope checking bracket 22. The rear guide wheel 25 is rotatably fixed on the rear rope checking bracket 22. The rear guide wheel 25 is provided with a second groove for limiting the square structure 20. The third connecting plate 23 is arranged on the outer side of the two rear guide wheels 25 and forms a third space suitable for limiting the square structure 20 with the rear rope checking bracket 22. The square structure 20 is penetrated in the third space. The top end of the square structure 20 is fixedly connected to the bottom end of the second bracket 21. The bottom end of the square structure 20 is penetrated in the rear rope checking bracket 22. One end of the second elastic member 24 abuts against the rear rope checking bracket 22, and the second elastic member 24 is sleeved on the bottom end of the square structure 20. Furthermore, the rear rope checking component 32 also includes a second hitting rod 19 and a buffer block 26. The buffer block 26 is arranged on the rear rope checking bracket 22. The bottom end of the square structure 20 passes through the buffer block 26 and the rear rope checking bracket 22 in sequence. The second hitting rod 19 is arranged at the top end of the second bracket 21 and is suitable for cooperating with the third switch and the fourth switch.

[0057] It can be understood that the square structural member 20 can be a square steel or other square structural member, the second elastic member 24 is a spring, two guide wheel shafts are installed on the rear rope inspection bracket 22, and two rear guide wheels 25 are respectively installed on the two guide wheel shafts. A square hole is formed between the two rear guide wheels 25. After the square steel and the second bracket 21 are connected, they pass through the square hole. The guide wheel and the second hitting rod 19 are installed on the second bracket 21. The square steel is passed through the square hole on the rear rope inspection bracket 22, and the spring is inserted from the bottom of the square steel, and locked with a nut to make the spring in a compressed state. The buffer block 26 is preferably a nylon top block, which can prevent the square steel from directly colliding with the rear rope inspection bracket 22 and making abnormal noises. The rear rope inspection component 32 is installed on the longitudinal beam 12 of the parking space, and the rear switch bracket 17 is installed on the rear rope inspection bracket 22. Two switches are installed on the rear switch bracket 17 to detect the position (the upper part is the third switch) and the loose rope (the lower part is the fourth switch).

[0058] Reference Figures 1 to 6 The method for using the rope checking device of the second aspect of the present application may be the method for using the rope checking device of the first aspect of the present application. The method for using the rope checking device comprises the following steps:

[0059] Two rear rope inspection components 32 are installed at the rear end of the parking space to detect the presence and looseness of the rear traction rope 30; since the steel wire rope at the rear hanging point does not change in angle, the detection is more accurate and convenient, and the structural design is also simpler.

[0060] Two front rope inspection components 31 are installed at the front end of the parking space, and the front traction rope 29 is passed through the first guide wheel 1. The first switch 15 and the second switch 16 are set at corresponding positions. When the combined force of the front traction rope 29 and the first elastic member 8 changes, the first bracket 2 will be activated, thereby detecting the loose rope through the first switch 15, and detecting the extreme position through the second switch 16. Since the steel wire rope at the front suspension point will change the angle and produce a displacement difference as the drum rotates, the front upper guide wheel 4 is designed to be a structure that can slide along the axis. The front rope inspection component 31 and the rear rope inspection component 32 can be used together to perfectly solve the problems of in-place, loose rope, and extreme detection of multi-layer lifting and transverse moving equipment, and have the characteristics of stability, reliability, and accurate detection.

[0061] Reference Figures 1 to 6 The working principle of the rope checking device of the first aspect of the present application is as follows:

[0062] When the vehicle loading plate 28 is in place, the wire rope is in a fully tightened state, the first guide wheel 1 of the front rope checking component 31 presses down the front traction rope 29, and the second guide wheel 18 of the rear rope checking component 32 presses down the rear traction rope 30. At this time, the first elastic member 8 and the second elastic member 24 are in a compressed state. When the vehicle loading plate 28 moves downward, the entire device is in a balanced state. Figure 1 , the angle θ of the front traction rope 29 pressed by the first guide wheel 1 will change from the minimum to the maximum. At this time, for the front rope inspection component 31, the front traction rope 29 drives the first guide wheel 1 and the first bracket 2 to move the round steel toward the center of the transverse frame 27 for a distance and rotate a certain angle. The front upper guide wheel 4 and the front lower guide wheel 6 work together. The front lower guide wheel 6 fixes the round steel, and the front upper guide wheel 4 moves axially with the round steel. The front upper guide wheel 4 and the front lower guide wheel 6 cooperate with the round steel to move, so that the round steel moves smoothly without jamming or noise, so that the device can operate well. For the rear rope inspection component 32, since there is no angle change, the square steel of the rear rope inspection component 32 does not move before the vehicle loading plate 28 lands. When the vehicle loading plate 28 moves from the lower position to the upper position, the angle of the front traction rope 29 pressed by the first guide wheel 1 will change from the maximum to the minimum, and the front rope inspection component 31 also undergoes the above-mentioned movement, but in the opposite direction. After the vehicle loading plate 28 leaves the ground, the square steel of the rear rope checking component 32 does not move.

[0063] In-place state: when the vehicle loading plate 28 descends to the ground, the vehicle loading plate 28 no longer exerts pulling force on the wire rope. At this moment, the motor has not stopped running yet, and the wire rope pressed by at least one of the first guide wheel 1 or the second guide wheel 18 is in a relaxed state. Since the spring is in a compressed state when the wire rope is tightened, the wire rope is relaxed at this moment. Under the action of the spring force, the guide wheel of the entire device moves downward with the round (square) steel, and at least one of the second hitting rod 19 of the rear rope checking component 32 or the first hitting rod 9 of the front rope checking component 31 triggers the in-place switch during the movement process. The switch feeds back a signal to the system, controls the motor to stop running, and realizes the control of the vehicle loading plate stopping in-place.

[0064] Rope break detection state: when the loading plate 28 is in the raised position, if the steel wire rope at the front hanging point breaks, under the action of the first elastic member 8, the first guide wheel 1 of the front rope checking component 31 moves downward with the round steel, thereby causing the first hitting rod 9 to trigger the rope break detection switch; if the steel wire rope at the rear hanging point breaks, under the action of the second elastic member 24, the second guide wheel 18 of the rear rope checking component 32 moves downward with the square steel, triggering the rope break detection switch; both of the above situations can cause the control main circuit to be powered off, the system reports a fault and cannot be started, thereby realizing the rope break detection function of the four steel wire ropes.

[0065] Limit state: when the in-position switch is triggered, the in-position switch fails abnormally and cannot transmit signals to the system. At this time, the motor continues to run, and the rod at the corresponding position continues to move downward under the action of the spring force. Regardless of the front rope detection component 31 or the rear rope detection component 32, the switch rod first triggers the broken rope detection switch. If the broken rope detection switch also fails, it continues to trigger the limit switch downward. The switch feeds back a signal to the system, thereby causing the system to report a fault and the motor stops running.
