Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of special equipment detection, and particularly relates to a detection device for safety pressure lever in amusement facilities. BACKGROUND

[0002] The safety pressure lever 12 is a special component distinguishing the amusement facilities from other ordinary mechanical and electrical equipment. In order to make the safety pressure lever 12 work reliably in the actual operation of the amusement facilities, load simulation test should be carried out. The common means in the industry at present is that when the safety pressure lever 12 is shaped, the load test of actual operation for a certain number of times (such as 60,000 times) is carried out first, and then the deformation and damage of the appearance are detected, the locking failure should not exist, and the fracture of the parts should not exist.

[0003] See Figure 2 and Figure 3 , application No. 201210170120.7 discloses a safety pressure lever test device. When the test device is used to carry out a load simulation test on the safety pressure lever 12, the safety pressure lever 12 needs to be locked by the locking device first, and then the hook 10 installed on the first oil cylinder 9 is used to hook the pull rod 11 installed on the safety pressure lever 12. The first oil cylinder 9 makes the hook 10 produce upward pulling force, and the first oil cylinder 9 exerts vertical pulling force on the safety pressure lever through the hook 10 and the pull rod 11, so as to simulate the vertical load generated by the amusement personnel when the amusement facilities run. Then, the first oil cylinder 9 makes the hook 10 reset downward, stops exerting vertical pulling force on the safety pressure lever 12, and starts the air cylinder 7 again after the locking device is released. The air cylinder 7 makes the safety pressure lever 12 rotate by 30 degrees once, so as to simulate the process that the safety pressure lever 12 releases the amusement personnel from the amusement facilities. Thus, the test of the safety pressure lever 12 is completed. After the above test is repeated for 60,000 times, the deformation and damage of the appearance are detected, the locking failure should not exist, and the fracture of the parts should not exist.

[0004] The shortcomings of the above test device are:

[0005] 1. When the safety pressure lever 12 is rotated each time to simulate the process that the person is released from the safety pressure lever 12, the extension amount of the first oil cylinder 9 also needs to be adjusted appropriately, so as to prevent the safety pressure lever 12 from colliding with the hook 10 on the first oil cylinder 9 in the process of rotating. The redundant operation of adjusting the extension amount of the first oil cylinder 9 causes inconvenience in the test process.

[0006] 2. Not only the air cylinder 7 is used to rotate the safety pressure lever 12, but also the pull rod 11 and the hook 10 are used to exert vertical load on the safety pull rod 11, so as to cause the structure of the detection device to be complex. UTILITY MODEL CONTENTS

[0007] The utility model discloses a detection device for safety pressure lever in amusement facilities can avoid using cylinder to make safety pressure lever rotate and avoid using hook to produce vertical load to safety pressure lever, make test device structure simplify, can also avoid repeatedly adjusting the operation of the first oil cylinder elongation, simplify test process.

[0008] The utility model discloses a detection device for safety pressure lever in amusement facilities, including work table, the upper surface of work table is equipped with the locking assembly for making safety pressure lever one end locking, the fixed mounting of work table has the suspension bracket, be equipped with the force assembly for exerting vertical load to safety pressure lever on the suspension bracket;

[0009] The force assembly comprises:

[0010] The stretching assembly is fixedly installed on the suspension bracket at a non-extensible end, and the extensible end faces downward; the stretching assembly can exert vertical load on the safety pressure lever;

[0011] The vertical plate is fixedly installed on the extensible end of the stretching assembly by the connecting frame;

[0012] The inclined plate is fixed at the lower end of the vertical plate; the end of the safety pressure lever away from the rotating shaft is designated as the P end, and the P end of the safety pressure lever abuts against the upper surface of the inclined plate; the direction in which the rotating shaft of the safety pressure lever is located is designated as the Y direction, and when viewed in the Y direction, the P end of the safety pressure lever is located at the right side of the vertical plate, the inclined plate is fixed on the right side surface of the vertical plate, and the right side surface of the vertical plate does not contact the P end of the safety pressure lever.

[0013] Further, when viewed in the Y direction, the upper end of the vertical plate is designated as point M, the lower end of the vertical plate is designated as point O, and the end of the inclined plate away from the lower end of the vertical plate is designated as point N, and then the angle MON is an obtuse angle.

[0014] Further, a circular ring is sleeved on the safety pressure lever, a pull rope is arranged on the circular ring, one end of the pull rope is tied to the circular ring, the other end of the pull rope is tied to the inclined plate, the pull rope is inelastic, and the pull rope is in a non-taut state.

[0015] When the stretching assembly malfunctions and the safety pressure lever cannot rotate and naturally reset by relying on its own gravity, the elongation of the stretching assembly is controlled artificially, the stretching assembly pulls the safety pressure lever to rotate through the taut pull rope and the circular ring, and the safety pressure lever can be passively reset under the action.

[0016] Further, the length of the inclined plate along the Y direction is longer than the length of the P end of the safety pressure lever along the Y direction.

[0017] The length of the P end of the safety pressure lever along the Y direction can be ensured to be in complete contact with the inclined plate at all times, and if the length of the inclined plate along the Y direction is shorter than the length of the safety pressure lever along the Y direction, a part of the safety pressure lever cannot be in contact with the inclined plate, and the P end of the safety pressure lever is not uniformly stressed along the Y direction when vertical load is generated.

[0018] Beneficial effects

[0019] 1、The detection device is provided with a vertical plate and an inclined plate, and under the premise that the locking device locks the safety press bar, if the vertical plate and the inclined plate are moved vertically through the stretching assembly, a vertical load is generated on the safety press bar, and the test of the vertical load of the safety press bar can be simulated.

[0020] 2、When simulating the process of releasing the safety press bar by a person, only the stretching assembly needs to be reset, then the locking device is released, and then the vertical plate and the inclined plate are continuously moved upward through the stretching assembly according to the needs, so that the safety press bar can rely on the horizontal shaft to rotate; during the resetting process, only the extension end of the stretching assembly needs to be moved downward, and then the safety press bar can rely on its own gravity to reset. The whole device saves the pull rod for installing the hook, avoids the problem of interference with the hook in the prior art due to the rotation of the safety press bar around the horizontal shaft, and also avoids the use of the air cylinder, so that the rotation of the safety press bar completely depends on the first oil cylinder, and the components of the detection device are simpler.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the present application will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0026] See Figure 1 , Figure 2 and Figure 3 , a detection device for a safety press bar in an amusement facility, comprising a workbench 1, and the workbench 1 is fixedly installed with a suspension 2.

[0027] In the plan view, the workbench 1 is rectangular. One side of the workbench 1 is along the X direction, and the other side adjacent to the side is along the Y direction.

[0028] See Figure 3 The workbench 1 is provided with a locking assembly for locking the safety pressure lever 12. The locking assembly belongs to the prior art. In the embodiment, the locking assembly includes:

[0029] The equipment rack 3 is installed on the upper surface of the workbench 1 by the clamp in the embodiment. The installation here means that the clamp is pressed on the workbench 1.

[0030] The horizontal shaft 4 is arranged on the equipment rack 3. The equipment rack 3 is provided with a hole for the horizontal shaft 4 to pass through. The axis of the horizontal shaft 4 coincides with the axis of the hole. The horizontal shaft 4 can rotate around the axis of the hole. The axis of the horizontal shaft 4 is along the Y direction. The equipment rack 3 does not cover the middle position of the horizontal shaft 4. The equipment rack 3 is only sleeved on both ends of the horizontal shaft 4 by the hole.

[0031] The two mounting ears 5 are respectively fixed on both ends of the horizontal shaft 4, and are fixedly connected with the corresponding end of the safety pressure lever to form an integral whole. The fixed connection is clamping or welding, etc.

[0032] The limiting plate 6 is provided with a through hole 8 along the Y direction. The limiting plate 6 is sleeved on the middle position of the horizontal shaft 4 by the through hole 8. The diameter of the through hole 8 is approximately equal to the diameter of the horizontal shaft 4. The diameter of the through hole 8 is slightly larger than the diameter of the horizontal shaft 4. The axis of the through hole 8 coincides with the axis of the horizontal shaft 4.

[0033] The second oil cylinder 13 is rotatably connected to the equipment rack 3 by a rotating shaft at the non-extendable end, and is rotatably connected to the upper end of the limiting plate 6 by a shaft A at the extendable end. The rotating shafts at both ends of the second oil cylinder 13 are along the Y direction.

[0034] The third oil cylinder 14 is rotatably connected to the equipment rack 3 by a rotating shaft at the non-extendable end, and is rotatably connected to the lower end of the limiting plate 6 by a shaft B at the extendable end. The rotating shafts at both ends of the third oil cylinder 14 are along the Y direction. In the Y direction, the points where the shaft A and the shaft B are located do not coincide with the point where the horizontal shaft 4 is located.

[0035] The locking process is: only the second oil cylinder 13 is shortened, or only the third oil cylinder 14 is shortened, or the second oil cylinder 13 and the third oil cylinder 14 are shortened at the same time, which will cause the axis of the perforation 8 on the limiting plate 6 to no longer coincide with the axis of the cross shaft 4, the inner wall of the perforation 8 is in close contact with the outer wall of the cross shaft 4, under the hydraulic pressure of the second oil cylinder 13 or the third oil cylinder 14, a large friction force is generated between the limiting plate 6 and the cross shaft 4, so that the safety pressure lever cannot rotate around the axis of the cross shaft 4 as a whole, thereby achieving the locking effect of the safety pressure lever. Because the inner wall of the perforation 8 is very close to the outer wall of the cross shaft 4, only a very small shortening amount of the second oil cylinder 13 and the third oil cylinder 14 is needed to complete the locking, and because only a very small shortening amount is needed, the second oil cylinder 13 and the third oil cylinder 14 do not need to consider motion interference when they are shortened at the same time, and only the gap between the parts can meet the purpose of the axis of the perforation 8 on the limiting plate 6 not coinciding with the axis of the cross shaft 4. The loosening process is that the second oil cylinder 13 and the third oil cylinder 14 are reset, so that the axis of the perforation 8 coincides with the axis of the cross shaft 4 again, and the action is completely opposite to the locking process, which will not be described again.

[0036] The above contents are all prior art and are not designed in the present scheme.

[0037] The innovation of the present embodiment is that the use of the air cylinder 7 is avoided, and in the present scheme, the force applying assembly for generating vertical load of the safety pressure lever is different from the prior art, and the present scheme can only rely on the force applying assembly to complete the rotation of the safety pressure lever 12 around the axis of the cross shaft 4, as shown in Figure 1 The force applying assembly of the present scheme comprises:

[0038] The stretching assembly, in the present embodiment, the stretching assembly is the first oil cylinder 9, and in other embodiments, the stretching unit can be other elements that can provide vertical tension force, the axis of the first oil cylinder 9 is arranged in the vertical direction, the non- telescopic end is fixed on the suspension 2, and the telescopic end faces downward.

[0039] The vertical plate 15 is vertically arranged and is fixed on the telescopic end of the first oil cylinder 9 through the connecting frame; in the Y direction, the lower end of the end of the safety pressure lever away from the cross shaft 4 is defined as the P end, the P end of the safety pressure lever is arranged on the right side of the vertical plate 15, and the P end of the safety pressure lever 12 cannot abut against the right side surface of the vertical plate 15, so as to ensure that the P end will not be interfered by the vertical plate 15 during the right rotation of the P end.

[0040] The inclined plate 16 is fixed on the lower end right side of the vertical plate 15, and in the Y direction, the inclined plate 16 is arranged below the P end, and the upper surface of the inclined plate 16 abuts against the P end. In order to ensure the stability when the inclined plate 16 abuts against the P end, the length of the inclined plate in the Y direction is longer than the length of the P end in the Y direction, so as to ensure that the P end can completely contact the inclined plate 16, and the inclined plate and the P end are in linear contact.

[0041] In the Y direction, the vertical plate and the inclined plate are regarded as a whole K, the shape of the whole K is similar to L type. The upper end of the vertical plate is point M, the lower end of the vertical plate is point O, and the end of the inclined plate away from the vertical plate is point N. The angle of angle MON is obtuse.

[0042] The detection process of the detection device is as follows:

[0043] The control assembly first locks the safety pressure lever 12 by the locking assembly. When the safety pressure lever 12 is locked, the control assembly is in the state of Figure 1 The control assembly is an existing control terminal with a set program. Then, the control assembly shortens the extension end of the first oil cylinder 9 upward, and the first oil cylinder 9 generates an upward load, such as 500N, on the P end of the safety pressure lever 12 through the inclined plate 16. Because the locking device keeps the safety pressure lever 12 in the locked state, the safety pressure lever 12 does not rotate around the horizontal shaft 4 at this time. At this time, the test of simulating the vertical load generated by the amusement personnel during the operation of the amusement facility is completed.

[0044] Then, the control assembly controls the extension end of the first oil cylinder 9 to extend downward, and the load on the safety pressure lever 12 is removed. The control assembly unlocks the locking device to allow the safety pressure lever 12 to rotate around the horizontal shaft 4. The control assembly shortens the extension end of the first oil cylinder 9 upward again, and the first oil cylinder 9 rotates the P end of the safety pressure lever 12 to the right through the inclined plate 16. Gradually, as the safety pressure lever 12 rotates, the P end of the safety pressure lever 12 is separated from the upper surface of the inclined plate 16, and correspondingly, the N end of the inclined plate 16 is in abutment with the safety pressure lever 12. However, it is ensured that the rotation angle of the safety pressure lever 12 around the horizontal shaft 4 is less than or equal to 30 degrees. At this time, because the safety pressure lever 12 has completed a rotation around the horizontal shaft 4, the test of simulating the safety pressure lever 12 releasing the amusement personnel from the amusement facility is simulated.

[0045] The above two tests are the load tests of the actual operation of the safety pressure lever 12.

[0046] Finally, the control assembly extends the extension end of the first oil cylinder 9 downward to reset, and the safety pressure lever 12 gradually rotates around the horizontal shaft 4 under the action of its own gravity and resets. After resetting is completed, the control assembly locks the safety pressure lever 12 again through the locking device.

[0047] The above operation is repeated a certain number of times, such as 6w times, to complete the load test of the actual operation of the safety pressure lever 12 multiple times. The surface of the safety pressure lever 12 that has completed the load test of the actual operation of the safety pressure lever 12 multiple times is detected to check whether there is deformation and damage in appearance. If there is locking failure, part fracture, etc., it is unqualified, otherwise it is qualified.

[0048] In addition, in order to prevent the P end of the safety pressure lever 12 from being excessively rotated to the right when the first oil cylinder 9 rotates the P end of the safety pressure lever 12 to the right, causing the safety pressure lever 12 to fail to return to the original position due to its own gravity, in the embodiment, the excessive rotation means that the P end of the safety pressure lever 12 is rotated to the right by an angle greater than a set threshold angle, such as 30 degrees. Therefore, a ring 17 is sleeved on the safety pressure lever 12, and the ring 17 is tied to the inclined plate 16 through a pull rope 18. One end of the pull rope 18 is tied to the ring 17, and the other end is correspondingly tied to the inclined plate 16. A hole is formed in the inclined plate 16 for the pull rope to pass through and be tied to the inclined plate. The pull rope 18 is not flexible, but has a certain slack in a non-tight state.

[0049] During normal testing, the inclined plate 16 does not apply any force to the safety pressure lever 12 through the pull rope 18 and the ring 17. Only when the first oil cylinder 9 is operated accidentally, such as when the program of the first oil cylinder 9 is wrong and the first oil cylinder 9 is shortened too much, causing the vertical plate 15 and the inclined plate 16 as a whole to be rotated to the right by too large an angle, the vertical plate 15 and the inclined plate 16 as a whole cannot return to the Figure 1 state due to gravity, the first oil cylinder 9 is manually controlled to be elongated, the pull rope 18 is first tightened, and then the first oil cylinder 9 pulls the safety pressure lever 12 to the left through the inclined plate 16, the tightened pull rope 18, and the ring 17, until the safety pressure lever 12 is returned to the Figure 1 state around the horizontal shaft 4. During normal testing, the first oil cylinder 9 is not operated accidentally, and the first oil cylinder 9 only rotates the safety pressure lever 12 around the horizontal shaft 4 by an angle less than 15 degrees, which is not enough to cause the safety pressure lever 12 to be excessively rotated, and the safety pressure lever 12 can return to the Figure 1 state due to its own gravity.

[0050] Based on the above ideal embodiments according to the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of the claims.
