Description

Technical Field

[0001] The utility model relates to the technical field of guide rail transportation, in particular to a guide rail transfer vehicle. Background Art

[0002] A guide rail is a device with grooves or ridges made of metal or other materials that can bear, fix, guide and reduce friction of moving devices or equipment. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine parts, special equipment, instruments, etc. Guide rails are also called slide rails, linear guides, and linear slides. They are used in linear reciprocating motion occasions and have higher rated loads than linear bearings. At the same time, they can bear a certain torque and can achieve high-precision linear motion under high load conditions.

[0003] At present, the guide rails of the guide rail transfer vehicles are mostly surface-supported, that is, there is surface contact between the guide rail and the transfer vehicle. After the guide rail is processed, some metal debris will adhere to its surface. If there is metal debris on the contact surface between the guide rail and the transfer vehicle, during the transportation process, when the guide rail and the transfer vehicle slide relative to each other, the metal debris will scratch the surface of the guide rail, thereby affecting the quality of the guide rail.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0025] like Figure 1-2 As shown, a guide rail transfer vehicle includes a frame 1, a wheel is provided at the bottom of the frame 1, and a handlebar 103 is provided at the end of the frame 1. An upper support plate 101 is provided at the upper end of the frame 1, and two parallel support rods 2 are provided at the upper end of the upper support plate 101, such as Figure 3 As shown, a semicircular support ring 201 for supporting the guide rail is provided at the upper end of the support rod 2. The cross section of the support ring 201 is circular, so that the support ring 201 and the guide rail are in point contact, reducing the contact area.

[0026] In order to improve the stability of the guide rail during transportation, a pressure rod 4 is provided between the two support rods 2 to press down the guide rail, which can prevent the guide rail from jumping. The lower end of the pressure rod 4 is an arc surface, and there is a line contact between the pressure rod 4 and the guide rail, and the contact area is small; a positioning rod 3 is provided on the outer side of the support rod 2 to position the end of the guide rail, which can prevent the guide rail from sliding with the support ring 201 during transportation. When the guide rail is not needed for transportation and is only placed on the frame 1 for storage, the pressure rod 4 and the positioning rod 3 are not needed.

[0027] like Figure 6 As shown, a slide rail 107 is provided at the upper end of the upper support plate 101, a lead screw 108 is connected between the end of the frame 1 and the support rod 2, a crank 109 is provided at the end of the lead screw 108, and a slider matched with the slide rail 107 and a nut sleeve matched with the lead screw 108 are provided at the lower end of the positioning rod 3. The lead screw 108 is rotated by the crank 109, and the lead screw 108 rotates to drive the nut sleeve to move, thereby realizing the position adjustment of the positioning sense.

[0028] A lower support plate 102 connected to the vehicle frame 1 is provided below the upper support plate 101 , and the lower support plate 102 is used for placing some tools, parts and other items.

[0029] A stud 104 is provided in the middle of the upper support plate 101. Figure 4 As shown, a sleeve 401 is provided in the middle of the pressure rod 4 and is sleeved on the outside of the stud 104. The sleeve 401 and the stud 104 can rotate. A first spring 105 is provided between the sleeve 401 and the upper support plate 101. The stud 104 is equipped with a clamping nut 106 for pressing the pressure rod 4 downward. The first spring 105 pushes the pressure rod 4 upward, and the pressure rod 4 is pressed downward by the clamping nut 106 to adjust the height of the pressure rod 4.

[0030] The side wall of the frame 1 is provided with a locking member 5 for fixing the pressure rod 4. Figure 5 As shown, the locking member 5 includes a support plate 502, a locking block 501 is provided at the upper end of the support plate 502, a locking groove 402 cooperating with the locking block 501 is provided at the end of the pressure rod 4, a pull rod 503 penetrating the side wall of the frame 1 is provided at the lower end of the support plate 502, a limit block 505 is provided at the end of the pull rod 503, and a second spring 504 is provided between the limit block 505 and the side wall of the frame 1.

When in use, the pressure rod 4 rotates 90 degrees to be parallel to the support rod 2. At this time, the support plate 502 is pulled to make the locking block 501 correspond to the locking groove 402. Under the action of the second spring 504, the locking block 501 cooperates with the locking groove 402 to fix the pressure rod 4.

[0032] When in use, place the guide rail in the support ring 201, support the two ends of the guide rail through the support ring 201, and one end of the guide rail is placed on one of the positioning rods 3. After the guide rail is placed, adjust the other positioning rod 3 so that the other positioning rod contacts the other end of the guide rail, rotate the pressure rod 4 so that the pressure rod 4 is located above the guide rail, and fix the angle of the pressure rod 4 through the locking member 5, and rotate the clamping nut 106 so that the pressure rod 4 just contacts the upper end surface of the guide rail. Push the frame 1 for transportation, open the locking member 5 after moving it into place, loosen the clamping nut 106, rotate the pressure rod 4 so that the pressure rod 4 is perpendicular to the support rod 2, open one of the positioning rods 3, and move the guide rail out of the support ring 201.
