[0030] Please refer to Figure 1-4 , in an embodiment of a vehicle-mounted working platform of the present utility model, the vehicle-mounted working platform includes a base assembly 1, a guardrail 2 and a gantry 3; slots 4 for inserting fork arms are respectively welded on the left and right sides of the lower surface of the base assembly 1. The fork arm is a mechanical structure in the prior art for supporting and moving heavy objects, and is often applied to equipment such as forklifts, agricultural machinery, and construction machinery. It usually consists of two parallel arms whose width can be adjusted. The slots 4 extend forward and backward, and a connection pin assembly 41 for restricting the fork arm from disengaging from the slots 4 is provided at the front end of the slots 4; guardrails 2 are respectively fixedly arranged on the front and rear sides of the upper surface of the base assembly 1, and gantries 3 are respectively rotatably arranged on the left and right sides of the upper surface of the base assembly 1; the guardrail 2 and the gantry 3 enclose a working platform on the base assembly 1, and the gantry 3 can be rotated to open and close the working platform.

[0031] In the use of this embodiment, the staff can enter and exit the working platform by rotating the gantry 3. Since there are two slots 4 for the fork arms to insert, and the two slots 4 are arranged at intervals on both sides of the bottom surface of the base assembly 1. After the two fork arms are inserted into the corresponding slots 4 and restricted by the connecting pin assembly 41, the provided supporting force is in the same vertical plane as the gravity of the staff and the working platform, so as to balance the supporting force, self-weight and the gravity borne by the working platform, prevent the working platform from tipping forward and backward, left and right, and further prevent the vehicle equipped with this working platform from tipping over.

[0032] Specifically, the guardrail 2 includes a middle support rod 21, a railing 22 and a cross connecting plate 23; Frame-shaped welding frames 14 are vertically and fixedly connected to the four corners of the base assembly 1 through bolts. The middle support rod 21 is vertically and fixedly connected to the middle edge of the base assembly 1. Two railings 22 are arranged up and down on both sides of the middle support rod 21. Two cross connecting plates 23 are welded to the upper and lower parts of the middle support rod 21. Each cross connecting plate 23 corresponds to a group of railings 22 arranged left and right. One end of the railing 22 is fixedly connected to the cross connecting plate 23 through a bolt, and the other end of the railing 22 is fixedly connected to the welding frame 14 through a bolt.

[0033] More specifically, the gantry 3 can be arranged between the front and rear two welding frames 14. One end of the gantry 3 is rotatably connected to one of the welding frames 14 through a hinge; A safety door lock 31 for locking and fixing the gantry 3 is provided on the other welding frame 14. The safety door lock 31 includes a connecting pin detachably connected to the gantry 3 and a U-shaped bent pipe rotatably connected to the welding frame 14. By rotating the U-shaped bent pipe downward, the middle part of the U-shaped bent pipe is sleeved on the gantry 3, and then the connecting pin is installed to restrict the upward rotation of the U-shaped bent pipe to disengage from the gantry 3, so as to close the gantry 3. Of course, the above safety door lock 31 can also adopt existing conventional door locks. In principle, as long as the effect of locking the gantry 3 can be achieved.

[0034] Further, the vehicle-mounted working platform of this embodiment further includes a safety tube 5 and a safety ring 51; The safety tube 5 is arranged on one side of the guardrail 2 along the length direction of the guardrail 2. The safety tube 5 is fixedly connected to the gantry 3 through bolts. When the length of the base assembly 1 is relatively long, multiple safety tubes 5 can also be arranged. The multiple safety tubes 5 are connected end to end through flanges; There are two safety rings 51, and both of the two safety rings 51 are sleeved on the safety tube 5. The staff can hang the safety hook on their body on the safety ring 51 to prevent falling from the working platform.

[0035] Please refer to Figure 1 and Figure 5, the connecting pin assembly 41 includes a positioning pin 411, a chain 412, and a plug pin 413; the positioning pin 411 penetrates through both sides of the slot 4, and this positioning pin 411 is used to pass through the through holes on the fork arms. One end of the positioning pin 411 is connected to the plug pin 413 through the chain 412, and the plug pin 413 can be inserted into the other end of the positioning pin 411; the connection point of the chain 412 and the positioning pin 411 and the insertion point of the plug pin 413 on the positioning pin 411 are respectively located on both sides of the slot 4. After the fork arms are inserted into the slot 4, first remove the plug pin 413, pass the positioning pin 411 through the slot 4 and the through holes on the fork arms from one side of the slot 4, and then insert the plug pin 413 into the end of the positioning pin 411 that penetrates through the other side of the slot 4, thereby restricting the fork arms from detaching from the slot 4.

[0036] Please refer to Figure 6 , the base assembly 1 includes a main base 11 and sub-bases 12 detachably connected to the left and right sides of the main base 11 respectively. Slots 4 are respectively arranged on the left and right sides of the lower surface of the main base 11, and the two sub-bases 12 are symmetrically arranged; the detachable connection method between the sub-base 12 and the main base 11 allows the sub-base 12 to be detached and separated from the main base 11 for transportation, and then reinstalled during use, thus facilitating transportation.

[0037] Please refer to Figure 6 and Figure 7 , the front and rear ends of the sub-base 12 can be respectively connected to the main base 11 through two symmetric connecting members 13. The connecting member 13 includes a connecting plate 131 and two clamping plates 132 spaced and welded on one side of the connecting plate 131. The connecting plate 131 is welded to the end face of the sub-base 12 or the main base 11, and the two clamping plates 132 are respectively close to both sides of the end of the sub-base 12 or the main base 11. During use, the two connecting plates 131 are spliced together, and then detachably connected through a plurality of bolts and nuts, so that the sub-base 12 and the main base 11 form a detachable connection. By installing the sub-base 12 in the above manner, the installation is convenient, and it is safe and reliable.

[0038] The usage method or working principle of the present utility model is as follows:

[0039] The staff first enters the working platform formed by the enclosure of the guardrail 2 and the gantry 3 on the base assembly 1 by rotating the gantry 3. Then, the driver inserts the two fork arms on the transport vehicle into the two slots 4. The staff then locks the fork arms through the connecting pin assembly 41 and locks the gantry 3 through the connecting member 13. Finally, it is lifted and transported to the destination by the transport vehicle.

[0040] Since the two slots 4 are arranged at intervals on both sides of the bottom surface of the base assembly 1, the supporting forces provided by the two fork arms and the gravity of the staff and the working platform are in the same vertical plane, thereby balancing the supporting force, self-weight, and the gravity borne by the working platform, preventing the working platform from tipping forward and backward or left and right, and further preventing the vehicle equipped with this working platform from tipping over.

[0041] The embodiments described above only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model.
