Description

Technical Field

[0001] The utility model relates to the technical field of forklift battery hoisting, in particular to an anti-falling hoisting device for transporting forklift batteries. Background Art

[0002] An electric forklift is a forklift that uses electricity to operate, and most of them work on batteries. A battery is a type of battery that can store limited electrical energy and use it in a suitable place. Its working principle is to convert chemical energy into electrical energy. It should be noted that it is best not to place the battery horizontally. When the battery is placed upright, the electrolyte can submerge the plates and there is still a little space left. If the battery is placed horizontally, part of the electrode plates will be exposed to the air, which is very bad for the battery plates. In addition, the observation hole of the general battery or the top of the battery has an exhaust port that is connected to the outside world, so the electrolyte is easy to flow out when the battery is placed horizontally.

[0003] Due to the special structure of the transfer forklift battery, it needs to be placed vertically when hoisted into the battery frame. Traditionally, when hoisting a single forklift battery, the entire upper end surface of the forklift battery is clamped. However, since the upper end surface of the forklift battery is relatively smooth, a rectangular rubber pad needs to be installed during hoisting to increase the anti-fall effect during hoisting. This results in a slower pre-fixation of the transfer forklift battery. The rectangular rubber pad needs to be replaced in time after repeated use, otherwise it is easy to cause the battery to fall during hoisting. For this reason, an anti-fall lifting device for transfer forklift batteries is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an anti-falling hoist for a transfer forklift battery, which solves the technical problems of slow pre-fixation and high cost of lifting the transfer forklift battery.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: an anti-falling sling for transporting forklift batteries, comprising an operating arm and a sling shell, wherein a clamping sling for hoisting the forklift battery is provided in the middle of the sling shell;

[0006] The clamping sling includes two vertical fixed plates symmetrically fixedly arranged in the middle of the lower end of the sling shell, a fixed shaft is fixedly arranged between the two vertical fixed plates, two squeezing sticks are symmetrically rotated in the middle of the fixed shaft, two L-shaped squeezing rods are symmetrically fixedly arranged in the middle of the sling shell, a lower pressure plate is fixedly arranged at the lower end of the L-shaped squeezing rod, and a driving component for driving the two squeezing sticks to open and close is arranged inside the sling shell.

[0007] Preferably, the driving assembly includes two U-shaped sliding blocks axially symmetrically slidably arranged inside the sling shell and two screw rods symmetrically rotatably arranged inside the sling shell, an I-shaped driving rod is rotatably arranged between the U-shaped sliding block and the extrusion rod, a threaded seat is arranged in the middle of the screw rod through a threaded connection sleeve, and the threaded seat and the U-shaped sliding block are fixedly connected through a connecting block;

[0008] A driving shell is also fixedly provided on one side of the middle part of the sling shell, a synchronous wheel is fixedly provided on one end of the screw rod inside the driving shell, and transmission is carried out between the two synchronous wheels through a synchronous belt, a driving motor is fixedly provided on one side of the middle part of the driving shell, and an output end of the driving motor is fixedly connected to one end of the rear screw rod.

[0009] Preferably, the rotation angle of the extrusion roller ranges from 0° to 30°.

[0010] Preferably, a rectangular groove is provided at the bottom of the sling shell to facilitate the rotation of the I-shaped driving rod.

[0011] Preferably, the lower ends of the two squeezing rollers are both in the shape of arc-shaped spikes.

[0012] Preferably, the upper end surface of the lower pressing plate is lower than the setting height of the fixed shaft, and a rubber pad is provided on the inner side surface of the lower pressing plate.

[0013] By means of the above technical solution, the utility model provides an anti-falling sling for transporting forklift batteries, which has at least the following beneficial effects:

[0014] 1. The utility model can change the traditional lifting method through the clamping sling, and use the mutual cooperation of the squeezing rod and the lower pressure plate to realize the limit of the forklift battery. During the lifting, there is no need to use a rectangular rubber pad to increase the friction force, thereby reducing the risk of the forklift battery falling during the lifting. At the same time, when the clamping sling is used, it only needs to directly insert the two squeezing rods into the exhaust port on the top of the forklift battery, and start the drive motor to realize the pre-fixation of the forklift battery before lifting, which greatly speeds up the lifting of multiple sets of forklift batteries into the frame.

[0015] 2. The utility model uses a single drive motor to drive the opening and closing of the two squeezing rods, which effectively reduces the manual participation during lifting. Moreover, through the cooperation of the screw and the threaded seat, the two squeezing rods have a certain stability after opening, which effectively prevents the risk of the forklift battery falling during lifting. At the same time, the setting of the two lower pressure plates greatly ensures the stability of the forklift battery, reduces the lateral swing of the forklift battery after being limited by the two squeezing rods, and enables the forklift battery to be accurately placed in any position in the battery frame.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] Please refer to Figure 1-Figure 3 , an anti-falling sling for transporting forklift batteries, comprising an operating arm 1 and a sling shell 2, wherein a clamping sling 3 for hoisting the forklift battery is provided in the middle of the sling shell 2;

[0026] The clamping sling 3 includes two vertical fixed plates 301 symmetrically fixedly arranged in the middle of the lower end of the sling shell 2, a fixed shaft 302 is fixedly arranged between the two vertical fixed plates 301, two squeezing rods 303 are symmetrically rotated in the middle of the fixed shaft 302, two L-shaped squeezing rods 311 are symmetrically fixedly arranged in the middle of the sling shell 2, a lower pressing plate 312 is fixedly arranged at the lower end of the L-shaped squeezing rod 311, and a driving component for driving the two squeezing rods 303 to open and close is arranged inside the sling shell 2; the driving component includes two U-shaped sliding blocks 304 axially symmetrically slidably arranged inside the sling shell 2 and two screw rods 306 symmetrically rotated arranged inside the sling shell 2, an I-shaped driving rod 305 is rotatably arranged between the U-shaped sliding block 304 and the squeezing rod 303, a threaded seat 307 is provided in the middle of the screw rod 306 through a threaded connection sleeve, and the threaded seat 307 is fixedly connected to the U-shaped sliding block 304 through a connecting block;

[0027] A driving shell 308 is also fixedly provided on one side of the middle part of the sling shell 2, a synchronous wheel 309 is fixedly provided on one end of the screw rod 306 inside the driving shell 308, and a synchronous belt is used to transmit the power between the two synchronous wheels 309. A driving motor 310 is fixedly provided on one side of the middle part of the driving shell 308, and the output end of the driving motor 310 is fixedly connected to one end of the rear screw rod 306;

[0028] When in use, the position of the clamping sling 3 is controlled by controlling the operating arm 1. Since the central axis of the operating arm 1 and the central axis of the two squeezing rods 303 are in the same vertical plane, the insertion position of the two squeezing rods 303 can be controlled by moving the operating arm 1. The operating arm 1 is controlled to make the two squeezing rods 303 insert into the vent holes on the top of the transfer forklift battery, and then the operating arm 1 is controlled to descend as a whole, thereby driving the sling shell 2 to descend, that is, the two squeezing rods 303 extend into the vent holes on the top of the transfer forklift battery until the inner sides of the two lower pressure plates 312 are aligned with the top of the transfer forklift battery. When the end faces are in contact, the lowering of the operating arm 1 is stopped, and the control button is pressed to make the driving motor 310 work. After the driving motor 310 is started, the screw rod 306 on the rear side is driven to rotate, and the rotation of the screw rod 306 can drive the synchronous wheel 309 on the rear side to rotate. Since the two synchronous wheels 309 are driven by a synchronous belt, the screw rod 306 on the front side is rotated. The rotation of the two screws 306 causes the two threaded seats 307 to move in the opposite direction. The movement of the threaded seats 307 can drive the I-shaped driving rod 305 to move in the vertical plane, thereby driving the extrusion stick at the lower end of the I-shaped driving rod 305. The two extrusion rods 303 are rotated with the central axis of the fixed shaft 302 as the rotation axis, and finally the two extrusion rods 303 are opened at opposite angles, that is, the opening of the two extrusion rods 303 is realized, and the opening of the two extrusion rods 303 makes the cross-sectional area of ​​the two extrusion rods 303 below the fixed shaft 302 larger, and then larger than the cross-sectional area of ​​the vent hole on the top of the transfer forklift battery, which firmly limits the top of the transfer forklift battery. At the same time, when the two extrusion rods 303 are opened, the transfer forklift battery can be slightly lifted up, and combined with the use of the two lower pressure plates 312, the transfer forklift battery can be more firmly secured. The upper end of the forklift battery is limited. After the transfer forklift battery is pre-fixed, the mobile operating arm 1 can lift and move the transfer forklift battery. Due to the arrangement of the screw 306 and the threaded seat 307, the stability of the transfer forklift battery during lifting and moving can be effectively guaranteed. At the same time, since the two squeezing rods 303 are inserted into the air vents on the top of the transfer forklift battery and opened, the limiting of the transfer forklift battery not only relies on the squeezing of the air vents, but also there is vertical squeezing of the two squeezing rods 303 by the overall top of the transfer forklift battery, which effectively prevents the situation of falling during lifting.

[0029] Embodiment 2

[0030] Please refer to Figure 2-Figure 5 This embodiment is basically the same as the first embodiment. This embodiment is made on the basis of the first embodiment and has the same beneficial effects as the first embodiment. The same parts can be referred to each other and will not be described in detail here.

[0031] The rotation angle range of the squeezing rod 303 is between 0° and 30°. The opening angle of the squeezing rod 303 depends on the size of the air vent on the top of the transfer forklift battery and the thickness of the squeezing rod 303 itself. The setting of the maximum opening angle of the squeezing rod 303 of 30° can match most transfer forklift batteries on the market, greatly improving the practicality of the entire clamping sling 3.

[0032] A rectangular groove is provided at the bottom of the sling shell 2 to facilitate the rotation of the I-shaped drive rod 305. Since the U-shaped sliding block 304, the I-shaped drive rod 305 and the extrusion rod 303 constitute a simple connecting rod mechanism, the movement of the I-shaped drive rod 305 is deterministic. The rectangular groove facilitates the movement of the I-shaped drive rod 305, thereby ensuring the usability of the entire clamping sling 3.

[0033] The lower ends of the two squeezing rods 303 are both in the shape of arc-shaped spikes. This arrangement can better facilitate the squeezing rods 303 to be inserted into the vent holes on the top of the battery of the transfer forklift.

[0034] The upper end surface of the lower pressure plate 312 is lower than the setting height of the fixed shaft 302, and the inner side surface of the lower pressure plate 312 is provided with a rubber pad. In order to better limit the battery of the transfer forklift, this setting is necessary. At the same time, the rubber pad is set to protect the upper surface of the transfer forklift battery.

[0035] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] Each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the above embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiments.
