Technical Field

[0001] The utility model relates to the technical field of transportation auxiliary devices, in particular to a limiting device for transportation equipment. Background Art

[0002] As one of the most basic transportation equipment, the trolley is simple in design but extremely practical. Despite the continuous advancement of modern material handling technology, the trolley is still an irreplaceable transportation tool due to its low cost, simple maintenance requirements, easy operation and light weight. The limit device of the trolley transportation equipment is a mechanism used to fix and locate the position of the trolley, aiming to improve work efficiency and ensure the orderliness of the production site.

[0003] In the existing limiting device of the trolley transportation equipment, the upper end surface of the vehicle plate is usually provided with a pallet and a baffle of fixed size, and the size of the baffle matches the pallet, thereby ensuring that the baffle can effectively cover the periphery of the pallet to prevent the goods from sliding or tipping over during transportation.

[0004] However, this device still has some defects. The fixed-size pallets and baffles limit the adaptability of the trolley to transport equipment of different sizes. When the size or shape of the transport equipment does not match the pallet and baffle, it cannot be effectively fixed, which may cause safety hazards during transportation.

[0005] Therefore, it is necessary to provide a limiting device for transportation equipment to solve the above technical problems. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a limiting device for transportation equipment that can be used in conjunction with multiple parts in a clamping assembly and an adjusting assembly to achieve clamping and limiting of transportation parts of different sizes, thereby improving the applicability of the transportation device.

[0009] Preferably, the first limit plate and the second limit plate are designed as T-shaped structures, and the ports on the first limit plate and the second limit plate are both open designs, and both end sides are provided with pre-tightening bolts, and the clamping plate is detachably distributed and installed on the first limit plate and the second limit plate through the pre-tightening bolts.

[0010] Preferably, rubber gaskets are provided on the end sides of the first limiting plate and the second limiting plate, and the rubber gaskets are completely attached to the end sides of the first limiting plate and the second limiting plate through Velcro.

[0011] Preferably, sliders are provided at both end sides of the first limiting plate and the second limiting plate, and the first limiting plate and the second limiting plate move left and right in the notch provided in the bottom frame through the sliders.

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

In actual use, the staff places the transport part in the rectangular placement area formed by the four clamping plates 205. When the transport part is straightened, the control motor 301 is started, and the positive and negative screw rods 302 are driven to rotate through the drive of the control motor 301. Through the rotation of the positive and negative screw rods 302, the two groups of first limit plates 201 and the two groups of second limit plates 202 provided at the two ends are driven to move toward each other, thereby driving the two groups of clamping plates 205 to move toward each other, thereby realizing the clamping and limiting fixation of the transport part.

[0027] By using the clamping assembly 200 in conjunction with multiple parts in the adjustment assembly 300, it is possible to clamp and limit transport parts of different sizes. Compared with the traditional method of usually setting a fixed-size pallet on the upper end surface of the vehicle plate, this device can stably clamp transport parts of different sizes, thereby ensuring stability and safety during transportation.

[0028] Second embodiment:

[0029] like Figure 3-4 As shown, the first limit plate 201 and the second limit plate 202 are designed as T-shaped structures, and the upper ports of the first limit plate 201 and the second limit plate 202 are both open designs, and both end sides are provided with pre-tightening bolts 204, and the clamping plate 205 is detachably distributed and installed on the first limit plate 201 and the second limit plate 202 through the pre-tightening bolts 204.

[0030] By using the first limiting plate 201 in coordination with the second limiting plate 202 and the pre-tightening bolt 204, and by designing the ports on the first limiting plate 201 and the second limiting plate 202 as openings, during actual installation, it is only necessary to fit the clamping plate 205 thereinto, and by cooperating with the threaded holes at the ends of the clamping plate 205 and the pre-tightening bolts 204 on the first limiting plate 201 and the second limiting plate 202, the clamping plate 205 can be quickly installed and disassembled, thereby facilitating replacement of the clamping plate 205 according to actual conditions.

[0031] Third embodiment:

[0032] like Figure 4 As shown, rubber gaskets 206 are provided on the end sides of the first limiting plate 201 and the second limiting plate 202. The rubber gaskets 206 are completely attached to the end sides of the first limiting plate 201 and the second limiting plate 202 by Velcro.

[0033] By arranging a rubber gasket 206 at the end of the clamping plate 205, the use of the rubber gasket 206 can prevent the possibility of clamping the clamping plate 205 when clamping the transported object. At the same time, by using the rubber gasket 206, the friction between the clamping plate 205 and the transported object can be increased when the clamping plate 205 clamps the transported object, thereby improving the stability and safety of the clamping. The rubber gasket 206 also has a certain buffering effect, which can reduce the impact force on the transported object during transportation and protect the transported object from damage.

[0034] Fourth embodiment:

[0035] like Figure 4-5 As shown, sliders 203 are provided at both ends of the first limiting plate 201 and the second limiting plate 202 , and the first limiting plate 201 and the second limiting plate 202 move left and right in the slot 106 provided in the bottom frame 105 through the sliders 203 .

[0036] By setting two groups of slots 106 on the four walls of the bottom frame 105, and respectively cooperating with the sliders 203 set at both ends of the first limit plate 201 and the second limit plate 202, when the first limit plate 201 and the second limit plate 202 move toward each other, the sliders 203 set at both ends move left and right in the slots 106, and the slots 106 provide a precise moving path for the slider 203, ensuring the stability and linearity of the first limit plate 201 and the second limit plate 202 when they move toward each other.

[0037] Fifth embodiment:

[0038] like Figure 1 As shown, a placement groove 103 is also provided on one side of the upper end surface of the loading vehicle 101, and the inner cavity of the placement groove 103 is separated by a partition.

[0039] In actual use, the placement slot 103 can be used to store some commonly used but small items, such as tools, parts, etc., so that these items are easy to obtain. At the same time, the provided partitions also avoid the chaos caused by randomly placing them on the trolley.

[0040] Sixth embodiment:

[0041] like Figure 1 As shown, a handle 102 is also installed on the end side of the loader 101 through a movable shaft, and a control box is provided at the lower end of the handle 102. Two control motors 301 are electrically connected to the control box through PLC programming.

[0042] The two control motors 301 are centrally controlled by the control box at the lower end of the handle 102, so that the operator can perform all necessary operations in one position, which greatly improves the convenience of operation. At the same time, the design of the control box can integrate various control buttons and switches, and reduce the possibility of misoperation through reasonable layout and marking.

[0043] Working principle: In actual use, the staff places the transport parts in the rectangular placement area formed by the four clamping plates 205. When the transport parts are straightened, the control motor 301 is started, and the drive of the control motor 301 is driven to drive the rotation of the positive and negative screw rods 302. The rotation of the positive and negative screw rods 302 drives the two groups of first limit plates 201 and the two groups of second limit plates 202 set at both ends to move toward each other, thereby driving the two groups of clamping plates 205 to move toward each other, thereby realizing the clamping, limiting and fixing of the transport parts.

[0044] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
