It can improve the convenience and safety of forklift battery maintenance and increase the safety of forklift operation.

[0033] like Figures 1 to 5As shown, a battery locking safety control device for a reach-type forklift includes: a box 60, a pressure plate 210, a lock hook 620, a vehicle body panel 20 and a forward oil cylinder 50. The forklift battery is arranged in the box 60, and the box 60 is arranged on a forklift mast support 40, and the forklift mast support 40 is slidably arranged on the forklift frame. A lock hook 620 is vertically arranged on the side of the box 60 facing the driver's operating position, and the end of the lock hook 620 away from the side of the box 60 can be movably clamped on the vehicle body panel 20 arranged around the forklift driver's seat. The driving shaft of the forward oil cylinder 50 is drivingly connected to the forklift mast support 40, and is used to drive the forklift mast support 40 to slide forward and backward along the forklift frame. The pressure plate 210 is arranged on the vehicle body panel 20 and is engaged with the end of the locking hook 620. When the pressure plate 210 is pressed down, the locking hook 620 is disengaged from the pressure plate 210, and then the hydraulic pressure of the forward cylinder 50 pushes the forklift mast support 40 forward, driving the forklift battery to disengage from the vehicle body panel 20 and move together with the mast support.

[0034] Specifically, the reach forklift includes: a frame 10, a body panel 20 arranged at the driver's operating position, a mast 30 arranged on a forklift mast support 40, a forward oil cylinder 50 driving the forklift mast support 40 to slide forward and backward, a box 60 is arranged on the forklift mast support 40, and moves with the forklift mast support 40. A battery is arranged in the box 60, and the battery is located in the middle and rear part of the forklift. When the forklift is running, the battery box and the body panel are locked by a pressure plate and a locking hook, so that the battery becomes part of the center of gravity of the forklift. When the battery needs to be charged or replaced, the battery box is disengaged from the body panel and then moved forward with the mast. The battery box moves forward and backward with the forward oil cylinder 50 driving the forklift mast support 40, so that the battery box 60 moves outward, so as to facilitate charging or replacing the battery, and vice versa. When the box body 60 needs to be moved outward, the lock hook 620 on the box body needs to be disengaged from the body panel. At this time, the pressure plate 210 set on the body panel needs to be pressed to separate the clamping connection between the pressure plate and the lock hook 620. Correspondingly, when charging is completed or a new battery is loaded, the battery moves backward together with the mast and is fixed to the body panel. The box body 60 moves backward following the forklift mast support 40 and approaches the body panel 20 until the lock hook 620 and the pressure plate 210 are clamped with each other. At this time, the battery is in a locked state and the forklift can operate normally. The device can improve the convenience and safety of forklift battery maintenance, can quickly determine whether the battery is in a locked state, and increase the safety of forklift operation.

[0035] Furthermore, the end of the locking hook 620 is an L-shaped hook structure. When the locking hook 620 is engaged with the pressing plate 210 , the bent portion of the end of the locking hook 620 is engaged with the top of the pressing plate 210 .

[0036] In actual application, the lock hook 620 is a hook with a guiding slope. When the driver operates the rearward movement switch, the battery box 60 moves backward together with the forklift mast support 40 to approach the vehicle body panel 20. When the bent hook of the lock hook 620 contacts the pressure plate 210, the pressure plate 210 rotates as the guiding slope of the bent hook of the lock hook increases, and the lock hook 620 and the 210 pressure plate are engaged.

[0037] Furthermore, the pressure plate 210 is a cantilever mounted L-shaped plate structure, the cantilever L-shaped end of the pressure plate 210 is used for the forklift driver to step on, the other end of the cantilever of the pressure plate 210 is provided with a through hole, and a rotating shaft 240 passes through the through hole, and the rotating shaft 240 is fixed on the vehicle body panel 20, so that the pressure plate 210 can rotate around the rotating shaft 240.

[0038] The device also includes: a mounting plate 230; the mounting plate 230 is a C-shaped structure, and both ends of the mounting plate 230 are fixed to the vehicle body panel 20; one end of the pressure plate 210 passes through the hollow part of the mounting plate, so that the rotation range of the pressure plate 210 is controlled by the hollow part of the mounting plate 230.

[0039] In actual application, the mounting plate 230 is a C-shaped plate, wherein both ends of the C-shape are fixed on the vehicle body panel 20, and the hollow portion of the C-shape is arranged to allow the cantilever of the pressure plate 210 to pass through, so that the rotation range of the pressure plate 210 is controlled by the hollow portion of the C-shaped plate.

[0040] The device also includes: a return spring 250; one end of the return spring 250 is arranged on the other end of the cantilever of the pressure plate 210, and the other end of the return spring 250 is arranged on the vehicle body panel 20. When the pressure plate 210 is stepped on by the driver, the return spring 250 is stretched. When the driver releases his foot, the pressure plate 210 returns to its initial position under the action of the restoring force of the return spring 250.

[0041] In actual application, the return spring 250 is a tension spring, one end of which is arranged on the pressure plate 210, and the other end is arranged on the middle part of the fixed vehicle body panel 20. When the pressure plate 210 is lightly stepped on by the driver, the return spring 250 receives the tension force to expand and contract, and when the driver releases his foot, the pressure plate 210 can return to the initial state under the action of the spring force.

[0042] The device further includes: a proximity switch 220 ; the proximity switch 220 is disposed on the mounting plate 230 and is used to detect the engagement state between the locking hook 620 and the pressing plate 210 .

[0043] The device further comprises: a controller; the controller is respectively connected with the proximity switch forklift instrument signal, and the controller controls the forklift instrument to display battery locking information when the proximity switch detects that the lock hook and the pressure plate are in a locked connection.

[0044] In actual application, the mounting plate 230 is provided with a mounting threaded hole for the proximity switch 220 to be installed, and the sensing distance can be adjusted so that the proximity switch 220 can sense the lock hook 620. When the lock hook 620 enters the pressure plate 210 and the two are engaged, the lock hook 620 enters the sensing range of the proximity switch 220, and the proximity switch 220 is turned on, sending an electrical switch signal to the controller. The proximity switch 220 can send a 0 or 1 electrical switch signal to the controller. When the proximity switch 220 is turned on, it is set to a 1 electrical switch signal.

[0045] When the controller receives the electric switch signal of 1, it sends a battery lock image signal to the instrument, which is convenient for the driver to intuitively judge the battery lock status. In addition, the controller removes the turtle speed mode restriction and allows the forklift to accelerate and decelerate at high power.

[0046] When the electric switch signal received by the control is 0, the lock hook 620 fails to enter the pressure plate 210, and the two are not in place, the controller's built-in judgment speed mode is limited to turtle speed. At this time, the instrument displays a turtle image, and the forklift is only allowed to accelerate and decelerate slowly.

[0047] Furthermore, a roller 410 is provided at the bottom of the forklift mast support 40, and a forklift mast is provided on the forklift mast support. When the forward cylinder drives the forklift mast support to slide, the forklift mast support slides forward and backward along the forklift frame through the roller.

[0048] Furthermore, support limit blocks 630 are provided around the bottom of the box body 60, and the box body 60 is fixed to the forklift mast support 40 through the support limit blocks 630, and a diagonal brace (not shown in the figure) is provided between the bottom surface of the box body and the forklift mast support to limit the moving direction of the box body.

[0049] In practical applications, the diagonal brace is a long structure in the shape of a slope, and the support limit block is a rectangular structure. The box body cooperates with the oblique block on the mast support through the friction force of the inclined surface on the diagonal brace, and is fixed on the mast support of the forklift. When the box body and the mast support of the forklift move backward under the thrust of the oil cylinder, the box body is close to the enclosure near the driver. At this time, the box body lock hook is engaged with the pressure plate on the body enclosure, the box body is fixed, and the instrument displays a locked figure. At this time, the bottom support limit block of the box body does not contact the forklift leg. When the mast support moves forward due to the thrust of the operating cylinder, the thrust of the oil cylinder overcomes the friction between the diagonal brace of the box body and the oblique block of the mast support, and the box body is separated from the mast support. Under the action of gravity, the bottom support limit block of the box body falls on the leg in the middle and rear part of the forklift. The box body, which is the center of gravity of a part of the forklift, is stably fixed in the middle and rear part of the forklift. At this time, the mast support moves forward under the action of the thrust of the oil cylinder. When the battery needs to be removed for charging or replacement, the mast support drives the mast to move forward and backward, but does not drive the box body to move together. When the battery needs to be replaced, the mast support is moved backward first, and then the driver operates the pressure plate to disengage the pressure plate from the lock hook, and then the battery can be taken out.

[0050] Furthermore, the other end of the cantilever of the pressure plate is in an imitation triangular plate structure, and the through hole is located above the connection position of the reset spring.

[0051] It can be seen that the utility model provides a battery locking safety control device for a reach-forklift, wherein the forklift battery is arranged in a box body, a locking hook is arranged on the box body, and the locking hook is engaged with a pressure plate arranged on the body panel, and when the pressure plate is pressed down, the locking hook is disengaged from the pressure plate, so that the forklift battery is disengaged from the body panel and moves together with the mast support. The problem of inconvenience and high labor cost in battery charging and replacement of existing reach-forklifts is solved. The convenience and safety of forklift battery maintenance can be improved, and the safety of forklift operation can be increased.
