[0029] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.
[0030] In the present invention, if no explanation is made to the contrary, the locative words included in the term such as "inside, outside" only represent the orientation of the term in the normal use state, or are common names understood by those skilled in the art, and It should not be seen as a limitation on this term.
[0031] See figure 1 , The present invention provides a new type of roller transport vehicle, the roller includes a roller 1 and a sleeve 2 sleeved on the roller 1, including a chassis 3, a push-pull arm 4 and a fixed frame;
[0032] The four corners of the bottom end of the chassis 3 are provided with cart wheels 5, the bottom end of the push-pull arm 4 is fixed to the chassis 3, and the top end extends upward so that an obtuse angle is formed between the push-pull arm 4 and the chassis 3. 105-120°;
[0033] The fixing frame is arranged at the top of the chassis 3, and the fixing frame includes a fixing cover 6 and a first vertical plate 7 and a second vertical plate 8 which are vertically fixed on the chassis 3; the height of the first vertical plate 7 is greater than that of the second vertical plate 8 height, one end of the fixed cover 6 is hinged to the top of the second vertical plate 8 so that the fixed cover 6 can rotate along the hinge and cooperate with the top of the first vertical plate 7 to form a cavity for placing the roller;
[0034] The inner side wall of the first vertical plate 7 is recessed inward to form a first blind hole, and the inner side wall of the fixed cover 6 is formed with a second blind hole. When the fixed cover 6 is closed, the first blind hole and the second blind hole are coaxial and uniform. Greater than the diameter of roller 1;
[0035] A cushion sponge pad 10 is provided on the top surface of the chassis 3 below the sleeve 2, and a friction limit rubber block 11 is provided between the fixed cover 6 and the outer wall of the sleeve 2; wherein,
[0036] An extension plate 12 extends outward at the connection between the chassis 3 and the push-pull arm 4, and the edge of the extension plate 12 is wrapped with an anti-collision rubber layer.
[0037] Through the above technical solution, the four corners of the bottom end of the chassis 3 are provided with cart wheels 5, and the bottom end of the push-pull arm 4 is fixed to the chassis 3, which is convenient for pushing the entire device during manual transportation. The inner side wall of the first vertical plate 7 is recessed to form a first blind hole, and the inner side wall of the fixed cover 6 is formed with a second blind hole. When using, insert one end of the roller 1 of the roller into the first blind hole to hold the roller 1 is in the horizontal position, and then cover the fixed cover 6. At this time, the second blind hole on the fixed cover 6 will be sleeved on the other end of the roller 1 of the roller, passing through the mutual of the first vertical plate 7 and the second vertical plate 8. Cooperate to fix the rollers tightly on the fixed frame, effectively avoiding the rolling of the rollers due to the shaking of the vehicle body during transportation, causing collision damage between each other. At the same time, a buffer sponge pad 10 is provided between the chassis 3 and the sleeve 2, and a friction limit rubber block 11 is provided between the fixed cover and the sleeve 2, so that the stability of the roller during transportation can be further improved. In addition, an extension plate 12 extends outwards at the connection between the chassis 3 and the push-pull arm 4, so that during manual transportation, you only need to gently step on the extension plate 12 with your feet and force downward to make the front end of the chassis 3 tilt up. It is very convenient to maneuver when going uphill or encountering obstacles, and moving forward smoothly.
[0038] In this embodiment, in order to be able to transport multiple rollers at one time to improve transportation efficiency and save production time, preferably, there are multiple first and second blind holes, and multiple first and second blind holes The blind holes are arranged horizontally and spaced apart on the first vertical plate 7 and the second vertical plate 8 respectively, and the first blind holes and the second blind holes correspond one to one.
[0039] Because the blind hole and the outer wall of the top end of the roller 1 will frequently contact, and in order to extend the service life of the roller 1 and the blind hole, the roller 1 and the blind hole are made of metal materials, so that frequent contact and mutual friction will cause deformation, It is not conducive to the assembly of the roller and the blind hole. In order to improve the stability after fixing, preferably, a rubber sleeve is provided in the first blind hole and/or the second blind hole, and the outer wall of the rubber sleeve is attached to the first blind hole and/or The inner diameter of the rubber sleeve on the inner wall of the second blind hole is larger than the diameter of the roller 1.
[0040] In addition, in order to facilitate the control of the moving timing of the roller transport vehicle to match different production timings, it is preferable that the cart wheel 5 is a self-locking wheel.
[0041] In addition, in order to facilitate the manual pushing of the roller transporter, preferably, the top end of the push-pull arm 4 extends in the horizontal direction to form a push-pull handle 9.
[0042] Further, in order to prevent slippage between the palm of the hand and the push-pull handle 9, preferably, the push-pull handle 9 is covered with a non-slip sleeve.
[0043] Furthermore, in order to further increase the friction between the palm of the hand and the push-pull handle 9, preferably, a plurality of anti-slip protrusions are arranged on the outer wall of the anti-slip sleeve.
[0044] The preferred embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details in the above-mentioned embodiments. Within the scope of the technical concept of the present invention, many simple modifications can be made to the technical solutions of the present invention. These simple modifications all belong to the protection scope of the present invention.
[0045] In addition, it should be noted that the various specific technical features described in the above-mentioned specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention is The combination method will not be explained separately.
[0046] In addition, various different embodiments of the present invention can also be combined arbitrarily, as long as they do not violate the idea of the present invention, they should also be regarded as the content disclosed in the present invention.
