Description

Technical Field

[0002] When an engine is placed on a pallet, it needs to be positioned to prevent it from moving left and right. The conventional positioning method is to weld a positioning bracket at each of the four corners of the pallet, then insert a pin into the positioning bracket and insert the pin into the engine body to achieve the positioning of the engine body. This method of manually welding brackets and inserting pins is simple and easy to operate, but there are also many defects.

[0003] For example, the height of the positioning bracket is generally higher than the height of the pallet. When stacking the pallets, due to the influence of the positioning bracket, the pallets are stacked in a staggered manner to avoid the problem of the overall height of the stacked pallets being too high or the number of stacked pallets being too small. However, the space at the pallet storage site is narrow, and a large number of pallets are stacked in a staggered manner, which not only takes up space, but the protruding parts of the pallets are also likely to scratch the operators. In addition, the pin is movably inserted into the positioning bracket, and its stability is poor, and it is easily affected by external vibrations, which is not conducive to the positioning of the engine and will cause problems affecting engine assembly.

Detailed implementation manner

[0029] The following combines embodiments to further describe the present invention, but does not constitute any limitation to the present invention. Any person's limited modifications within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0030] Refer to Figures 1-7 , a folding positioning device for supporting an engine of the present invention, and positioning devices are installed at the four corner ends of the tray 5. The positioning device includes a connecting seat 1, a support rod 2, a mounting seat 3, and a positioning pin 4. The connecting seat 1 is detachably installed on the tray 5. Specifically, a mounting plate 17 is welded below the connecting seat 1, and the mounting plate 17 is installed on the tray 5 through bolts, so that the whole positioning device can be detached from the tray 5, facilitating the replacement of the corresponding positioning device according to different models. The height of the connecting seat 1 is less than the thickness of the tray 5, so that after the trays 5 are stacked, two adjacent trays 5 can contact each other without staggering stacking.

[0031] The support rod 2 is hinged to the connecting seat 1. Among them, the connecting seat 1 is composed of a connecting plate 14 and two mounting ears 15. The connecting plate 14 is welded between the two mounting ears 15 to form a groove with a cross-section similar to a U shape. A rotating shaft is installed between the two mounting ears 15, and the support rod 2 is rotatably connected to the rotating shaft to realize the hinged connection between the support rod 2 and the connecting seat 1. In this embodiment, when the support rod 2 is in a vertical state, the opposite sides of the connecting plate 14 and the two mounting ears 15 are in one-to-one correspondence with the three corresponding sides of the support rod 2, which can effectively improve the stability of the support rod 2 during use.

[0032] A first positioning structure for positioning the support rod 2 in the vertical direction is installed on the outer side of the connecting seat 1. The first positioning structure includes a threaded seat 11 and a positioning bolt 12. The threaded seat 11 is welded to one side of the connecting seat 1, and the positioning bolt 12 is screwed into the threaded seat 11. Positioning holes 13 for inserting the positioning bolt 12 are provided on both the connecting seat 1 and the support rod 2. When positioning the support rod 2, by rotating the positioning bolt 12, the positioning bolt 12 is inserted into the positioning holes 13 of the connecting seat 1 and the support rod 2 in sequence, and finally penetrates through the side of the connecting seat 1 away from the threaded seat 11, thereby realizing the positioning of the support rod 2. This positioning method is simple to operate, practical and reliable.

[0033] A second positioning structure 16 is provided on one side of the connecting seat 1 for positioning the support rod 2 that is flipped to be parallel to the surface of the tray 5.

[0034] In this embodiment, the second positioning structure 16 includes a support seat 161, a V-shaped block 162, a movable rod 163 and a second spring 164. The support seat 161 is installed on the tray 5. A positioning through groove arranged along the flipping direction of the support rod 2 is provided in the support seat 161, and the width of the positioning through groove is greater than the width of the support rod 2. V-shaped blocks 162 are provided on both sides of the positioning through groove. One end of the V-shaped block 162 is provided with a movable rod 163. The movable rod 163 is movably inserted into the support seat 161, and a limiting piece 165 is provided at the end of the movable rod 163 away from the positioning through groove. A second spring 164 is provided between the V-shaped block 162 and the support seat 161. The minimum distance between the two V-shaped blocks 162 is less than the width of the support rod 2.

[0035] When the support rod 2 needs to be flipped and folded, after loosening the positioning bolt 12, the support rod 2 can be directly pushed to flip. When the support rod 2 flips onto the V-shaped block 162, it will hit the V-shaped block 162. Due to the elastic installation of the two V-shaped blocks 162, under the extrusion of the support rod 2, both V-shaped blocks 162 move away from the support rod 2, and the second spring 164 contracts. When the distance between the two V-shaped blocks 162 is equal to the width of the support rod 2, the support rod 2 will continue to flip and fall, and finally fall to the bottom of the positioning through groove. At this time, the two V-shaped blocks 162 will push against the support rod 2 under the spring force of the second spring 164, thereby positioning the support rod 2 and avoiding the phenomenon that the support rod 2 rotates freely during the movement of the tray 5.

[0036] As Figure 4 shown, when the support rod 2 flips to a position parallel to the surface of the tray 5, the support rod 2 is below the minimum distance position of the two V-shaped blocks 162, but the upper end surface of the support rod 2 is above the lowest position of the two V-shaped blocks 162. Such a setting enables the support rod 2 to be directly lifted and flipped from the support seat 161, without too much operation, and is very convenient to use.

[0037] Preferably, a rubber pad 166 is provided at the bottom of the positioning through groove to avoid the problem of excessive noise caused by the rigid collision between the support rod 2 and the support seat 161 when the support rod 2 flips and falls, and at the same time, it also plays a role in buffering and protecting the support rod 2.

[0038] The mounting seat 3 is installed at one end of the support rod 2 away from the connecting seat 1, and the positioning pin 4 is movably inserted into the mounting seat 3; a pin gear shifting structure with two gears is provided in the mounting seat 3. Among them, when the positioning pin 4 is located in the first gear of the pin gear shifting structure, the end of the positioning pin 4 is located outside the mounting seat 3 to position the engine on the tray 5. That is, at this time, the positioning pin 4 is inserted into the engine, thereby realizing the positioning of the engine. When the positioning pin 4 is located in the second gear of the pin gear shifting structure, the positioning pin 4 is received in the mounting seat 3.

[0039] The pin gear shifting structure includes a connecting transverse groove 6, a first gear groove 7, and a second gear groove 8 all opened on the mounting seat 3. A plug hole penetrating through both ends of the mounting seat 3 is opened in the mounting seat 3, and the connecting transverse groove 6, the first gear groove 7, and the second gear groove 8 are all communicated with the plug hole. The first gear groove 7 and the second gear groove 8 are respectively communicated with the connecting transverse groove 6 to form a gear shifting channel. The positioning pin 4 is movably inserted into the plug hole, and a gear lever 9 is installed on the positioning pin 4, and the gear lever 9 is movably connected with the gear shifting channel.

[0040] When the gear lever 9 is located in the first gear groove 7, the positioning pin 4 is in the first gear state to realize the positioning of the engine on the tray 5. When the gear lever 9 is located in the second gear groove 8, the positioning pin 4 is in the second gear state, and the positioning pin 4 is received in the mounting seat 3.

[0041] Preferably, a limiting structure 10 for limiting the gear lever 9 located in the first gear groove 7 to the first gear groove 7 is installed on the outer wall of the mounting seat 3 to avoid the problem that the gear lever 9 exits from the first gear groove 7 and affects the positioning of the engine, thereby improving the reliability of the positioning device.

[0042] In this embodiment, the limiting structure 10 includes an inner mounting sleeve 101 and an outer movable sleeve 102. The inner mounting sleeve 101 is fixedly installed on the outer wall of the mounting base 3. A sliding groove 103 penetrating the outer movable sleeve 102 is provided in the outer movable sleeve 102, and closing plates 104 are installed at both ends of the sliding groove 103. Specifically, the closing plates 104 are installed at both ends of the outer movable sleeve 102 by screws for limiting the outer movable sleeve 102 to prevent the outer movable sleeve 102 from sliding out of the inner mounting sleeve 101 and falling off. The inner mounting sleeve 101 is slidably connected to the sliding groove 103. Further, a slide rail is provided on the outer side of the inner mounting sleeve 101, and a chute matching the slide rail is provided on the inner wall of the outer movable sleeve 102. A first spring 105 is provided between one end of the inner mounting sleeve 101 and the corresponding closing plate 104. The first spring 105 is an arc-shaped spring, and its two ends are respectively welded to the closing plate 104 and the inner mounting sleeve 101. A V-shaped elastic piece 106 is installed in the inner mounting sleeve 101. Specifically, one side of the V-shaped elastic piece 106 is welded in the inner mounting sleeve 101. The positioning head 107 of the V-shaped elastic piece 106 movably penetrates the inner mounting sleeve 101, a through hole 108 adapted to the positioning head 107 is provided on the upper surface of the outer movable sleeve 102, and the height of the positioning head 107 is greater than the sum of the thicknesses of one side side walls of the inner mounting sleeve 101 and the outer movable sleeve 102.

[0043] As Figure 4 shown, when the shift lever 9 is not located in the first gear slot 7, the positioning head 107 of the V-shaped elastic piece 106 is inserted into the through hole 108, thereby realizing the positioning of the outer movable sleeve 102 and making the outer movable sleeve 102 located on the periphery of the gear shifting channel. At this time, the first spring 105 is in a contracted state.

[0044] When the shift lever 9 is located in the first gear slot 7, the positioning head 107 can be pressed downwards to disengage it from the through hole 108. At this time, under the action of the first spring 105, the outer movable sleeve 102 will move along the outer wall of the mounting base 3 towards the first gear slot 7 and finally press against the shift lever 9, thereby realizing the positioning of the shift lever 9 and avoiding the risk that the shift lever 9 freely moves during use and disengages from the first gear slot 7. When the outer movable sleeve 102 presses against the shift lever 9, and the structure is as Figure 6 shown.

[0045] Preferably, a elastic piece 109 is fixedly installed on the mounting base 3. The end of the elastic piece 109 extends above the positioning head 107, and a raised pressing block 110 is provided below the end of the elastic piece 109 to facilitate the staff to press the positioning head 107 and avoid the situation that it is easy to scratch the fingers when pressing by hand.

[0046] Preferably, the convex pressing block 110 is conical. That is, the contact area between the convex pressing block 110 and the positioning head 107 is smaller than the end face area of the positioning head 107, which can effectively avoid the problem that the positioning head 107 rebounds back into the through hole 108.

[0047] The working principle of the present invention is as follows: After placing the engine on the tray 5, ensure that the support rod 2 is in a vertical state, and the outer movable sleeve 102 is in a locked state by the positioning head 107 of the V-shaped elastic piece 106 in the inner mounting sleeve 101. Then operate the gear lever 9 to move it into the first gear slot 7. At this time, the end of the positioning pin 4 will extend out of the mounting seat 3 and be inserted into the engine, thereby realizing the positioning of the engine. After the gear lever 9 is located in the first gear slot 7, press the elastic piece 109. The convex pressing block 110 below the elastic piece 109 presses down the positioning head 107 to disengage it from the through hole 108, releasing the lock on the outer movable sleeve 102. After the lock is released, the outer movable sleeve 102 will move along the outer wall of the mounting seat 3 towards the first gear slot 7 under the action of the first spring 105 and finally press against the gear lever 9, thereby realizing the positioning of the gear lever 9.

[0048] When it is necessary to release the positioning of the engine, pull the outer movable sleeve 102 towards the inner mounting sleeve 101. When the through hole 108 on the outer movable sleeve 102 corresponds to the position of the positioning head 107, due to the tension of the open end of the V-shaped elastic piece 106, the positioning head 107 will be inserted into the through hole 108, thereby realizing the positioning of the outer movable sleeve 102. At this time, just move the gear lever 9 from the first gear slot 7 to the second gear slot 8.

[0049] When it is necessary to stack and store the tray 5, first rotate the positioning bolt 12 to remove it from the support rod 2 to release the lock on the support rod 2. After releasing the support rod 2, push the support rod 2 to make it flip. When the support rod 2 flips and falls into the support seat 161, the V-shaped block 162 in the support seat 161 will press and position it. As for how the V-shaped block 162 realizes the positioning of the support rod 2, its working principle has been described in detail above, so it will not be elaborated here. After completing the flipping and positioning of the support rod 2, the tray 5 can be stacked.

[0050] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which will not affect the implementation effect of the present invention and the practicability of the patent.
