TECHNICAL FIELD

[0001] The utility model relates to grab bucket technical field, specifically, relates to grab bucket anti -toppling device. BACKGROUND

[0002] Grab bucket is a kind of mechanical equipment for material handling, is widely used in port, mine, construction site and logistics center etc. It is usually installed on crane or excavator, and the opening and closing action is controlled by hydraulic system to grab, lift and carry bulk material or large object. The design of grab bucket is different according to its use, for example: waste grab bucket is suitable for processing metal waste;Coal grab bucket is optimized for coal loading and unloading;Wood grab bucket is used for wood handling.

[0003] Grab bucket in storage and operation process, indeed there is due to improper operation, uneven ground or equipment failure etc. The risk of toppling, not only can lead to serious personnel casualty accident, also can cause equipment damage, and bring economic losses to enterprise. Port usually adopts wooden wedge as anti -toppling device, this traditional method although can prevent grab bucket from toppling to a certain extent, but wooden material is easy to be damped and corroded in port environment, gradually loses its effectiveness with the passage of time, especially in humid and high-salt coastal areas, the service life of wooden wedge can be greatly shortened, thereby increasing the security risk. CONTENT OF UTILITY MODEL

[0004] In order to overcome the shortcoming that traditional wooden wedge is easy to be damped and corroded in port and leads to short service life, the purpose of the utility model is to provide a kind of grab bucket anti -toppling device suitable for humid and high-salt coastal areas.

[0005] Technical scheme is as follows: grab bucket anti -toppling device, including base, connecting shaft, support plate, connecting seat, support rod and connecting spring, the top and right side of base are open, one side of base is rotatably connected with connecting shaft, connecting shaft is fixedly connected with support plate, support plate is embedded in the top opening of base, support plate is provided with gripping hole, support plate is connected with connecting seat, connecting seat is rotatably connected with support rod, the inside of base is provided with clamping groove for clamping support rod, connecting spring is connected between support plate and base.

[0006] Further, the number of clamping grooves is at least two, and the clamping grooves are arranged in the left-right direction of the base.

[0007] Further, it further includes non-slip pad, the bottom of base is connected with non-slip pad, and the bottom of non-slip pad is provided with a plurality of protrusions.

[0008] Further, it further includes rubber pad, and the rubber pad is connected to the support plate.

[0009] Further, it further includes pull block, and the pull block is connected in the gripping hole.

[0010] Furthermore, it also includes a pedal, with the pedal connected to the side of the base away from the connecting shaft.

[0011] This utility model has the following advantages: Compared with wooden wedge anti-tipping devices, this utility model is not easily affected by moisture and decay, can be reused, saves on usage costs, and can avoid personal injury and equipment damage caused by tipping. At the same time, this utility model can prevent tipping of different grabs, improve utilization rate, and by setting a connecting spring, the support plate can be quickly retracted into the base, and the support plate can also be prevented from rotating at will.

[0017] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0018] Grab anti-tipping device, such as Figures 1-4As shown, the device includes a base 1, a connecting shaft 2, a support plate 3, a connecting seat 4, a support rod 5, a connecting spring 7, an anti-slip pad 8, a rubber pad 9, a pull block 10, and a pedal 11. The top and right side of the base 1 are open. The connecting shaft 2 is fixedly connected to the right side of the base 1, and the support plate 3 is rotatably connected to the connecting shaft 2. The size and shape of the opening at the top of the base 1 are the same as the size and shape of the support plate 3. The support plate 3 fits into the opening at the top of the base 1. A gripping hole is opened at the top of the support plate 3, and a pull block 10 is fixedly connected to the gripping hole. A gap is left between the pull block 10 and the gripping hole, allowing the support plate 3 to rotate easily. The connecting seat 4 is fixedly connected to the bottom left side of the support plate 3, and a pull block 10 is rotatably connected to the connecting seat 4. The support rod 5 has a slot 6 inside the base 1 for engaging the support rod 5. There are five slots 6, which are spaced apart along the left and right sides of the base 1. A connecting spring 7, which is a helical spring, is fixedly connected between the support plate 3 and the base 1. An anti-slip pad 8 is fixedly connected to the bottom of the base 1. The anti-slip pad 8 has multiple protrusions on its bottom. The anti-slip pad 8 can increase the friction between the device and the ground and prevent the device from slipping and causing the grab bucket to tip over. A rubber pad 9 is fixedly connected to the top of the support plate 3. The rubber pad 9 can increase the friction between the support plate 3 and the grab bucket and prevent the grab bucket from slipping and tipping over. A pedal 11 is fixedly connected to the side of the base 1 away from the connecting shaft 2.

[0019] Initially, the connecting spring 7 is in its normal position. When using this device, first step on the pedal 11, place your hand into the gripping hole, and then rotate the support plate 3 upwards along the connecting shaft 2 using the pull block 10. This stretches the connecting spring 7. Next, rotate the support rod 5 so that it is positioned within one of the slots 6, thus unfolding the device. Stepping on the pedal 11 prevents the connecting spring 7 from moving the base 1, ensuring the device unfolds correctly. This allows the support plate 3 to fit tightly against the outer wall of the grab bucket, supporting the grab bucket and improving its safety and stability during storage. This reduces equipment damage and personal injury caused by the grab bucket tipping over. By using the support rod… The support plate 3 can be adjusted by engaging different slots 6 to change its tilt angle, thus adapting to different grabs. When the device needs to be retracted, manually hold the pull block 10 to rotate the support plate 3 upwards again, further stretching the connecting spring 7 and moving the support rod 5 away from the slot 6. Then release the support plate 3, and the connecting spring 7 returns to its original state, allowing the support plate 3 to retract into the opening of the base 1. It can be flexibly unfolded and retracted as needed, making it convenient to carry and use, further improving the safety level. In addition, the device has low manufacturing cost, simple structure, and is easy to install, disassemble and maintain. It can also be reused multiple times and is not easily damaged by moisture or corrosion.

[0020] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
