Description

Technical Field

[0001] The utility model relates to the technical field of vehicle detection equipment, in particular to a forklift detection equipment. Background Art

[0002] Forklift detection equipment is a device used to test the performance of forklifts, which is often used to detect the lifting speed, lowering speed and lifting height of the fork plate of the forklift. Forklift detection equipment usually includes an elevated frame and a laser detector. The laser detector is set in the center above the elevated frame. The driver will drive the forklift to be detected into the elevated frame so that the fork plate of the forklift is aligned with the laser detector. The laser detector will emit a laser beam, which will irradiate the fork plate of the forklift. When the laser beam irradiates the fork plate and reflects back to the sensor, the laser detector will calculate the time difference from the laser emission to the reception, and then use the relationship between the speed of light and the time difference to calculate the distance between the target fork plate and the laser detector. By continuously measuring this distance and recording the time, the lifting speed, lowering speed and lifting height of the fork plate can be calculated. In the prior art, when the driver drives the forklift into the elevated frame, he needs to constantly adjust the posture of the forklift to accurately align the fork plate of the forklift with the transmitting end of the laser detector on the elevated frame, so that the laser beam emitted by the laser detector can be shot on the fork plate. This method, which requires the operator to repeatedly adjust the posture of the forklift to align with the laser detector, takes a lot of time and is not conducive to improving the detection efficiency of the forklift. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a forklift detection device, which is conducive to improving the detection efficiency of the forklift.

[0004] The forklift detection device according to the embodiment of the utility model includes:

[0005] Bracket;

[0006] A laser detector, the laser detector is arranged above the bracket, and the laser detector can be slidably arranged on the bracket in the left-right direction;

[0007] A slide plate, wherein the slide plate is slidably connected to the bracket in the left-right direction, the distance between the left end of the slide plate and the emitting end of the laser detector in the left-right direction is smaller than the width of the fork plate of the forklift, and a guide slope is provided on the left end of the slide plate, the guide slope faces backward, and the guide slope is used to abut against the fork plate of the forklift so that the slide plate can move to the right;

The laser detector in the forklift detection device can move along the left and right directions with the slide board, so that the fork plate of the forklift only needs to abut against the left end of the slide board, and the laser beam emitted by the laser detector can be projected onto the fork plate of the forklift, so that the driver does not need to spend a lot of time adjusting the posture of the forklift, and can quickly align the fork plate of the forklift with the transmitting end of the laser detector, and then can quickly detect the lifting speed, lowering speed and lifting height of the fork plate of the forklift, which is beneficial to improving the detection efficiency of the forklift.

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

[0033] In the description of the present invention, 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 the present invention based on the specific content of the technical solution.

[0034] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention.

[0035] refer to Figures 1 to 3 The forklift detection device of the utility model comprises:

[0036] Bracket 100;

[0037] The laser detector 300 is disposed above the bracket 100 and can be slidably disposed on the bracket 100 in the left-right direction;

[0038] The slide plate 110 is connected to the bracket 100 in a sliding manner in the left-right direction. The distance between the left end of the slide plate 110 and the emitting end of the laser detector 300 in the left-right direction is less than the width of the fork plate of the forklift. A guide slope 111 is provided on the left end of the slide plate 110. The guide slope 111 faces backward and is used to abut against the fork plate of the forklift so that the slide plate 110 can move to the right.

[0039] The transmission assembly 200 and the laser detector 300 are connected to the slide plate 110 through the transmission assembly 200, so that when the slide plate 110 moves to the right, the laser detector 300 can move to the right synchronously, and the laser beam generated by the laser detector 300 can be projected onto the fork plate of the forklift.

[0040] It is understandable that when the forklift needs to be detected, the driver only needs to align the fork plate of the forklift with the guide slope 111 on the left end of the slide 110, and then drive the forklift towards the direction close to the slide 110, that is, the forklift moves from the back to the front. In the process of the forklift moving forward, the fork plate of the forklift will abut against the guide slope 111 on the left end of the slide 110. Since the guide slope 111 is inclined and faces the rear, the slide 110 will gradually move to the right during the movement of the forklift under the action of the guide slope 111 and the fork plate. Since the laser detector 300 can be slidably connected to the upper part of the bracket 100 in the left-right direction, and the laser detector 300 is transmission-connected to the slide 110 through the transmission assembly 200, the laser detector 300 can move to the right synchronously during the movement of the slide 110 to the right. Because the distance between the emission end of the laser detector 300 in the left-right direction is smaller than the width of the fork plate of the forklift, the laser beam emitted by the laser detector 300 can be projected onto the fork plate abutting against the left end of the slide plate 110, so that the laser detector 300 can measure the distance between the fork plate and the laser detector 300, and then calculate the lifting speed, lowering speed and lifting height of the fork plate. The laser detector 300 in the forklift detection device can move along the left-right direction with the slide plate 110, so that when the fork plate of the forklift only needs to abut against the left end of the slide plate 110, the laser beam emitted by the laser detector 300 can be projected onto the fork plate of the forklift, so that the driver does not need to spend a lot of time to adjust the posture of the forklift, and can quickly align the fork plate of the forklift with the emission end of the laser detector 300, and then can quickly detect the lifting speed, lowering speed and lifting height of the fork plate of the forklift, which is conducive to improving the detection efficiency of the forklift.

[0041] Furthermore, the laser detector 300 is connected to the slide plate 110 through the transmission assembly 200, so that when the slide plate 110 moves to the right or left, the laser detector 300

[0042] Furthermore, the driver does not need to align the fork plate of the forklift with the guide slope 111 on the left end of the slide 110 during the driving process. The driver can first drive the forklift and extend the fork plate of the forklift into the bracket 100, and then the driver controls the forklift to turn right so that the fork plate of the forklift abuts against the left end of the slide 110. At this time, the laser beam emitted by the laser detector 300 can be projected on the fork plate abutting against the left end of the slide 110. It can be seen from this that the forklift detection device can enable the driver to quickly align the fork plate of the forklift with the laser detector 300, which is conducive to improving the detection efficiency of the forklift.

[0043] refer to Figure 3The forklift detection device includes a first slider 120 and a first slide rail 130. The first slide rail 130 is parallel to the left and right directions. The first slide rail 130 is arranged on the bracket 100. The first slider 120 is arranged on the slide plate 110. The first slider 120 is slidably connected to the first slide rail 130, so that the slide plate 110 can be slidably connected to the first slide rail 130 along the left and right directions through the first slider 120. The forklift detection device also includes a fastener and an elastic member 160. The left end of the elastic member 160 is connected to the slide plate 110, and the right end of the elastic member 160 is connected to the bracket 100. The fastener is used to fix the first slider 120 on the first slide rail 130. It can be understood that when the fork plate of the forklift moving forward abuts against the guide inclined surface 111 on the left end of the slide plate 110, the slide plate 110 will gradually move to the right, and the elastic member 160 is compressed at this time. The compressed elastic member 160 can provide a leftward thrust to the slide plate 110, so that the left end of the slide plate 110 can always abut against the fork plate of the forklift, avoiding a gap between the fork plate of the forklift and the left end of the slide plate 110, so that the laser beam emitted by the laser detector 300 can be projected on the fork plate abutting against the left end of the slide plate 110. After the forklift is moved into position, the driver can fix the first slider 120 to the first slide rail 130 by fasteners, so as to avoid the slide plate 110 from moving left and right when the fork plate moves up and down, and ensure that the laser beam emitted by the laser detector 300 can always be projected on the fork plate when the fork plate moves up and down.

[0044] As an embodiment of the utility model, the fastener is a bolt, a threaded hole is provided on the first slider 120, a through hole 113 is provided on the slide plate 110, the bolt is passed through the through hole 113 and is threadedly connected with the inner wall of the threaded hole, and the bolt can abut against the first slide rail 130, so that the first slider 120 is fixed to the first slide rail 130 by the bolt. It is understandable that the driver can tighten the bolt so that one end of the bolt presses against the first slide rail 130. Under the action of the bolt, the friction between the first slide rail 130 and the first slider 120 will increase, and the bolt will also hinder the sliding of the first slider 120, so that the first slider 120 is fixed on the first slide rail 130, and the slide plate 110 cannot slide left and right. When the next forklift needs to be inspected, the driver only needs to loosen the bolt to allow the slide plate 110 to slide in the left and right directions.

[0045] refer to Figure 2 The forklift detection device includes a second slider 140 and a second slide rail 150. The second slide rail 150 is parallel to the left and right direction. The second slide rail 150 is arranged on the bracket 100. The laser detector 300 is connected to the second slider 140. The second slider 140 is slidably connected to the second slide rail 150 so that the laser detector 300 can be slidably connected to the second slide rail 150 along the left and right direction through the second slider 140.

[0046] refer to Figure 4 and Figure 5 The transmission assembly 200 includes a rack 210, a gear 220, a first pulley 230, a second pulley 240, a third pulley 250, a fourth pulley 260, a first belt 270 and a second belt 280. The rack 210 is parallel to the left and right directions, and the teeth of the rack 210 face downward. The rack 210 is arranged on the skateboard 110, and the gear 220 is rotatably arranged on the bracket 100. The gear 220 and the rack 210 are meshed with each other. The first pulley 230 is coaxial with the gear 220 and is connected to the gear 220. The second pulley 240 is arranged at the first pulley 230. At the top, the second pulley 240 is arranged on the right side of the second slider 140, the second pulley 240 is rotatably arranged on the bracket 100, the third pulley 250 is coaxial with the second pulley 240 and connected to the second pulley 240, the fourth pulley 260 is arranged on the left side of the second slider 140, the fourth pulley 260 is rotatably arranged on the bracket 100, the first belt 270 is wound around the first pulley 230 and the second pulley 240, the second belt 280 is wound around the third pulley 250 and the fourth pulley 260, and the second slider 140 is connected to the second belt 280.

[0047] It can be understood that the axes of the gear 220, the first pulley 230, the second pulley 240, the third pulley 250 and the fourth pulley 260 are all parallel to the front-rear direction. The skateboard 110 moves rightward under the action of the fork plate, and the skateboard 110 can drive the rack 210 to move rightward. Since the rack 210 and the gear 220 are meshed with each other, and since the gear 220 is connected to the first pulley 230, the rack 210 moving rightward can drive the gear 220 and the first pulley 230 to rotate. Since the first belt 270 is wound around the first pulley 230 and the second pulley 240, the rotating first pulley 230 can drive the first belt 270 and the second pulley 240 to rotate. Since the third pulley 250 is connected to the second pulley 240, the second pulley 240 can drive the third pulley 250 to rotate. Since the second belt 280 is wound around the third pulley 250 and the fourth pulley 260, the third pulley 250 can drive the second belt 280 and the fourth pulley 260 to rotate, and because the second slider 140 and the second belt 280 are connected, the second belt 280 can drive the second slider 140 to move rightward. Specifically, the second slider 140 is connected to the upward portion of the second belt 280 between the third pulley 250 and the fourth pulley 260.

[0048] As an embodiment of the utility model, the transmission assembly 200 further includes a plurality of first tension wheels and a plurality of second tension wheels, wherein the plurality of first tension wheels are rotatably connected to the bracket 100, and the plurality of first tension wheels are pressed against the first belt 270, and the plurality of second tension wheels are rotatably connected to the bracket 100, and the plurality of second tension wheels are pressed against the second belt 280. It can be understood that the plurality of first tension wheels are pressed against the first belt 270, and the plurality of second tension wheels are pressed against the second belt 280, and the first tension wheels and the second tension wheels can increase the tensioning force of the first belt 270 and the second belt 280 respectively, which not only avoids the first belt 270 from slipping relative to the first pulley 230 and the second pulley 240, but also avoids the second belt 280 from slipping relative to the third pulley 250 and the fourth pulley 260.

[0049] refer to Figure 3 The forklift detection device further includes a roller 112, which is parallel to the up-down direction. The upper and lower ends of the roller 112 are rotatably connected to the left end of the slide 110. The outer wall of the roller 112 is tangent to the guide slope 111. The outer wall of the roller 112 is used to abut against the fork plate of the forklift. It can be understood that as the forklift moves, the fork plate will be separated from the abutment with the guide slope 111 and abut against the outer wall of the roller 112. Since the upper and lower ends of the roller 112 are rotatably connected to the left end of the slide 110, the fork plate that continues to move forward will drive the roller 112 to rotate, so that the original dynamic friction between the fork plate and the guide slope 111 is converted into rolling friction, reducing the friction between the fork plate and the left end of the slide 110, thereby reducing the wear of the fork plate and the slide 110.

[0050] As an embodiment of the present invention, a ladder is provided on the bracket 100, and the ladder extends to the upper end of the bracket 100. It is understandable that the maintenance personnel can climb to the upper end of the bracket 100 through the ladder, so that the maintenance personnel can repair the laser detector 300.

[0051] In the utility model, the laser detector 300 includes a laser transmitter, a laser receiver, a time measurement module and a processor. The laser transmitter is used to generate a laser beam so that the laser beam can be projected onto the fork plate. This component is used to receive the reflected laser beam. The laser receiver is used to receive the laser beam reflected from the fork plate and convert the laser signal into an electrical signal. The time measurement module is used to measure the time difference from the emission to the reception of the laser beam. The processor processes and calculates the received electrical signal to calculate the lifting speed, lowering speed and lifting height of the fork plate of the forklift.

[0052] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
