[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are 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] In order to facilitate understanding of the forklift spreader and forklift provided by the utility model, their application background is first explained. The forklift is a device used for loading, unloading, transporting and stacking goods in ports, cargo yards, warehouses and other places. The forklift spreader is a structure on the forklift used to lock and transport goods. In the related art, the forklift spreader is generally provided with a telescopic beam structure so that it has left and right, up and down freedom, thereby improving the application scope of the forklift.
[0025] However, in actual applications, it is found that when there is a front-to-back deviation of the goods, the forklift vehicle needs to move forward and backward to compensate for this degree of freedom to hang the box. This process has at least the following problems.
[0026] 1. The vehicle needs to be braked repeatedly for short distances, which is very time-consuming, laborious and inconvenient.
[0027] 2. Excessive forward movement of the vehicle will cause the spreader to push the container, posing a safety risk.
[0028] Therefore, how to improve work efficiency and optimize the work process has become an important issue that needs to be solved urgently.
[0029] Based on the above problems and findings, the utility model provides a forklift sling and a forklift, which can greatly reduce the operating difficulty of the forklift, optimize the operation process, and improve the operating efficiency.
[0030] Combine the following Figure 1 The utility model describes a forklift sling and a forklift.
[0031] Reference Figure 1 A forklift spreader includes a spreader body 1, a hook assembly 2, an adjustment mechanism 3 and a first drive member 4; wherein the spreader body 1 can provide installation positions for various components, forming the bottom support of the entire structure, and the hook assembly 2, the adjustment mechanism 3 and the first drive member 4 are all installed on the spreader body 1, forming the working part of the forklift spreader.
[0032] The hook assembly 2 includes a first hook 20 and a second hook 21 which are rotatably matched with the sling body 1, wherein one end of the first hook 20 and the second hook 21 extends out of the sling body 1 to form a locking end, which is used to cooperate with the locking hole on the cargo, and the first hook 20 and the second hook 21 can rotate around their respective rotation axes so that their respective locking ends swing on the horizontal plane to achieve locking or disengagement of the locking ends with the locking holes; at least one of the first hook 20 and the second hook 21 is slidably matched with the sling body 1 to form a sliding hook, and the adjustment mechanism 3 is used to adjust the distance that the locking end of the sliding hook extends out of the sling body 1; the first driving member 4 is used to drive the first hook 20 and the second hook 21 to rotate.
[0033] In a specific application scenario, when a forklift is used to carry goods such as containers, the spreader body 1 supports the first hook 20 and the second hook 21 to gradually approach the container, and the first hook 20 and the second hook 21 are respectively corresponding to the positions of the locking holes on the upper and lower containers, and then the first driving member 4 drives the first hook 20 and the second hook 21 to rotate around their respective rotation axes, so that their respective locking ends swing and are respectively locked with the locking holes on the two containers; when there is a deviation in the positions of the upper and lower containers in the front and rear directions, the adjustment mechanism 3 can be used to adjust the distance by which the locking ends of the first hook 20 and / or the second hook 21 that are slidably matched on the spreader body 1 extend out of the spreader body 1, so that the locking end of the sliding hook corresponds to the position of the locking hole on the container, and then the first driving member 4 drives the locking end of the sliding hook to lock with the locking hole on the container; compared with the related art, there is no need to repeatedly move the whole vehicle forward and backward for adjustment, which simplifies the operation difficulty, optimizes the operation process, and improves the operation efficiency. In addition, it effectively avoids the safety hazards caused by the spreader pushing the container due to the forward and backward movement of the whole vehicle.
[0034] Reference Figure 1 The adjusting mechanism 3 includes a guide portion 30 and a second driving member 31; wherein the guide portion 30 is rotatably connected to the spreader body 1, the first driving member 4 is connected to the guide portion 30, and is used to drive the guide portion 30 to rotate, and the sliding hook is slidably connected to the guide portion 30. In this way, the sliding hook and the spreader body 1 can be rotated and slidably matched at the same time; the second driving member 31 is used to drive the sliding hook to slide on the guide portion 30, so as to adjust the distance that the locking end of the sliding hook extends out of the spreader body 1, thereby giving the forklift spreader a degree of freedom in the front and rear directions.
[0035] It is understandable that the sliding hook and the guide portion 30 have a variety of optional connection methods. For example, the two can adopt a sliding groove and a slider, a linear guide rail and a slider, etc., which can be selected according to actual needs and application scenarios.
[0036] In a specific embodiment of the utility model, a hook guide groove is provided on the guide part 30, and the hook guide groove extends along the sliding direction of the sliding hook. A slider is slidably fitted in the hook guide groove, and the sliding hook is fixedly connected to the slider. Through the hook groove and the slider, the sliding of the sliding hook can be restricted and guided, thereby improving the stability and smoothness of the sliding of the sliding hook.
[0037] The cross-section of the hook guide groove can be T-shaped, U-shaped, dovetail-shaped, etc. The slider is adapted to the shape of the hook guide groove and embedded in the hook guide groove. In this way, the sliding of the slider can be constrained in the first direction, further improving the sliding stability of the sliding hook.
[0038] Of course, the connection methods between the sliding hook and the guide part 30 are not limited to the above-mentioned connection methods. Other connection methods can be used as long as they can achieve the sliding connection of the sliding hook on the hook guide groove.
[0039] In actual application, the second driving member 31 drives the sliding hook to slide on the guide portion 30, so as to adjust the distance that the locking end of the sliding hook extends out of the spreader body 1, thereby providing the forklift spreader with freedom in the front-to-back direction.
[0040] There are many options for the second driving member 31, for example, any form of linear driving element such as a pneumatic cylinder, an oil cylinder, a linear motor, etc. In this embodiment, the second driving member 31 adopts an oil cylinder, and the piston rod of the oil cylinder is connected to the slider. The slider is driven by the oil cylinder to slide in the hook guide groove to realize the forward and backward sliding of the sliding hook.
[0041] In order to further improve the working efficiency, in a specific embodiment of the utility model, the stacker spreader also includes a sensor and a controller; wherein the sensor is used to detect the distance between the locking end of the first hook 20 and the second hook 21 and the lock hole on the container, and generate and send a detection signal; the controller is connected to the sensor and the adjustment mechanism 3 for receiving the detection signal, and based on the detection signal, sends a control instruction to the adjustment mechanism 3, and the adjustment mechanism 3 adjusts the distance of the sliding hook extending out of the spreader body 1 according to the control instruction, so that the locking end of the sliding hook corresponds to the position of the lock hole on the cargo. Through the sensor and the controller, the first hook 20 and the second hook 21 can be accurately positioned, so that the rotary lock operation of the hook assembly 2 can be realized quickly and stably.
[0042] In a specific embodiment of the utility model, the first hook 20 is located directly above the second hook 21. The first hook 20 is used to cooperate with the lock hole on the lower side of the upper container, and the second hook 21 is used to cooperate with the lock hole on the upper side of the lower container. Through the joint action of the first hook 20 and the second hook 21, two containers can be transported. Based on different needs and application scenarios, the first hook 20 and the second hook 21 can have different combinations:
[0043] In one solution, the first hook 20 can be slidably matched with the spreader body 1 to form the above-mentioned sliding hook, and the second hook 21 is rotatably connected to the spreader body 1. In actual work, the second hook 21 located below is used as the working reference, and the distance that the locking end of the first hook 20 extends out of the spreader body 1 is adjusted by the adjustment mechanism 3 to provide the forklift spreader with freedom in the forward and backward directions, without adjusting the position of the container or repeatedly moving the entire vehicle forward and backward for adjustment.
[0044] In another solution, the first hook 20 and the second hook 21 can be slidably matched with the sling body 1 to form the above-mentioned sliding hook. With this arrangement, in actual work, the distances by which the locking ends of the first hook 20 and the second hook 21 extend out of the sling body 1 can be adjusted at the same time to provide the forklift sling with freedom in the forward and backward directions.
[0045] In another feasible solution, the second hook 21 can be slidably matched with the sling body 1 to form the above-mentioned sliding hook, and the first hook 20 is rotatably connected to the sling body 1. In such an arrangement, in actual work, the upper hook, i.e., the first hook 20, is used as the working reference, and the distance that the locking end of the second hook 21 extends out of the sling body 1 is adjusted through the adjustment mechanism 3 to provide the forklift sling with freedom in the forward and backward directions.
[0046] The above three solutions can be selected according to actual needs and application scenarios, but in this embodiment, for ease of understanding and explanation, the first solution is taken as an example for detailed explanation, and the connection relationship of each component in the other two solutions refers to the first solution.
[0047] Reference Figure 1 The first hook 20 is slidably connected to the guide part 30, specifically connected to the slider; the second hook 21 is rotatably connected to the spreader body 1; the first driving member 4 is simultaneously connected to the guide part 30 and the second hook 21, and is used to drive the guide part 30 and the second hook 21 to rotate. In this way, the first driving member 4 can simultaneously drive the first hook 20 and the second hook 21 to rotate, so as to achieve the locking and separation of the hook assembly 2 and the lock hole on the container.
[0048] In a specific embodiment of the utility model, the first driving member 4 can be a linear driving element of any form such as a cylinder, an oil cylinder, an electric push rod, etc. The output end of the first driving member 4 is connected to the guide part 30 and the second hook 21 by a crank-connecting rod mechanism. The linear drive of the first driving member 4 can be converted into a rotational motion of the first hook 20 and the second hook 21 through the crank-connecting rod mechanism, thereby realizing the rotation of the first hook 20 and the second hook 21.
[0049] In another specific embodiment of the present invention, the first driving member 4 can also be a rotary driving element in any form, such as an electric motor, a hydraulic motor, etc., to drive the guide portion 30 and the second hook 21 to rotate.
[0050] In a specific application scenario, the sling body 1 supports the first hook 20 and the second hook 21 to gradually approach the container. The sensor can detect the distance between the locking ends of the first hook 20 and the second hook 21 and the lock hole on the container in real time and transmit the detection signal to the controller. After the second hook 21 is in place, the sensor sends a control instruction to the adjustment mechanism 3 based on the detection signal. The second drive member 31 drives the first hook 20 to slide on the guide part 30 until the locking end of the first hook 20 corresponds to the position of the lock hole on the lower side of the upper container. After the first hook 20 is extended into place, the first drive member 4 drives the first hook 20 and the second hook 21 to rotate and lock the container, so as to carry out subsequent container transfer work.
[0051] The forklift provided by the utility model is described below. The forklift described below and the forklift sling described above can be referred to each other.
[0052] A forklift comprises the forklift sling mentioned above.
[0053] The novelty of the present utility model is that when there is a deviation in the positions of the upper and lower containers in the front-to-back direction, the distance that the locking ends of the sliding hook, i.e. the first hook 20 and / or the second hook 21, which are slidably fitted on the sling body 1, extend out of the sling body 1 can be adjusted by the adjusting mechanism 3, so that the locking end of the sliding hook corresponds to the position of the locking hole on the container, and then the locking end of the sliding hook is driven by the first driving member 4 to lock with the locking hole on the container; compared with the related art, there is no need to repeatedly move the whole vehicle forward and backward for adjustment, which simplifies the operation difficulty, optimizes the operation process, and improves the operation efficiency. In addition, it effectively avoids the safety hazard caused by the sling pushing the container due to the forward and backward movement of the whole vehicle.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
