DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-4 , the utility model provides a roller bed conveyor for heavy cargo transportation, comprising two bases 1;

[0024] A plurality of conveying rollers 2 are rotatably arranged between the two bases 1, and the plurality of conveying rollers 2 are transmitted through a driving mechanism 3 to drive the plurality of conveying rollers 2 to rotate synchronously. A limiting mechanism 4 for assisting the conveying of goods is arranged on the base 1, and legs 5 are fixedly arranged under the two bases 1, and a supporting mechanism 6 for increasing the overall stability is arranged on the legs 5;

[0025] The limiting mechanism 4 includes a first fixed seat 41 installed above the base 1, and a threaded rod 42 is penetrated and threadedly connected to the surface of the first fixed seat 41. One end of the threaded rod 42 is rotatably connected to the limiting seat 43. A guide assembly 44 is provided on the base 1. The limiting seat 43 moves linearly above the base 1 through the guide assembly 44. The surface of the limiting seat 43 is rotatably provided with a plurality of rollers 46 that contact the side wall of the cargo through a connecting arm 45.

[0026] The support mechanism 6 includes a connection seat 61 fixedly mounted on the surface of the support leg 5, a support rod 62 is penetrated through the surface of the connection seat 61, the support rod 62 is slidably arranged inside the connection seat 61 through an elastic component 63, an anti-slip pad 64 is installed at the bottom of the support rod 62, the elastic component 63 includes a connection ring 631 fixedly mounted on the surface of the support rod 62, the outer wall of the connection ring 631 is attached to the inner wall of the connection seat 61, a spring 632 is sleeved on the surface of the support rod 62, and the two ends of the spring 632 are fixedly connected to the connection ring 631 and the inner wall of the connection seat 61 respectively;

[0027] Specifically, when the whole is placed on the ground, the anti-skid pad 64 will be squeezed. Since the bottom of the anti-skid pad 64 is in contact with the ground, the anti-skid pad 64 will drive the support rod 62 to move upward inside the connecting seat 61 after being squeezed. At this time, the support rod 62 will drive the connecting ring 631 to move synchronously inside the connecting seat 61, and the spring 632 will be compressed between the connecting ring 631 and the connecting seat 61. Therefore, the elastic force of the spring 632 can make the anti-skid pad 64 close to the ground, thereby increasing friction.

[0028] The driving mechanism 3 includes a motor 31 and a rotating shaft 32 fixedly arranged at one end of the conveying roller 2. The motor 31 is fixedly arranged on one of the bases 1 and connected to one of the conveying rollers 2. Synchronous wheels 33 are fixedly arranged on the multiple rotating shafts 32. Two adjacent synchronous wheels 33 are driven by a synchronous belt 34.

[0029] Specifically, the motor 31 can drive one of the conveying rollers 2 to rotate. Since the five conveying rollers 2 are driven by the synchronous wheel 33 and the synchronous belt 34, the motor 31 can drive the five conveying rollers 2 at the same time to convey the goods.

[0030] The guide assembly 44 includes a second fixed seat 441 fixedly arranged on the base 1, a limiting rod 442 fixedly arranged on the limiting seat 43, and one end of the limiting rod 442 penetrates and is slidably arranged on the surface of the second fixed seat 441;

[0031] Specifically, when the threaded rod 42 rotates, it may drive the limit seat 43 to rotate synchronously, but because the limit rod 442 is slidably set on the second fixed seat 441, the limit seat 43 cannot rotate in the circumferential direction of the threaded rod 42, so that the limit seat 43 can only move in a straight line in the axial direction of the threaded rod 42.

[0032] A stabilizing seat 7 is fixedly disposed below the supporting legs 5, and a reinforcing rod 8 is fixedly disposed between the supporting legs 5 below the two bases 1;

[0033] Specifically, the stabilizing seat 7 can increase the overall stability, and the provision of the reinforcing rod 8 can increase the overall structural strength.

[0034] Working principle: the motor 31 can drive one of the conveyor rollers 2 to rotate. Since the five conveyor rollers 2 are driven by the synchronous wheel 33 and the synchronous belt 34, the motor 31 can drive the five conveyor rollers 2 at the same time to convey the goods. When the goods are placed on the conveyor roller 2, the support legs 5 and the stabilizing seat 7 will be squeezed. At the same time, the pressure on the support rod 62 will squeeze the anti-skid pad 64 through the connecting seat 61 and the support rod 62. Since the bottom of the anti-skid pad 64 is in contact with the ground, the anti-skid pad 64 will drive the support rod 62 to move upward inside the connecting seat 61 after being squeezed. At this time, the support rod 62 will drive the connecting ring 631 to move synchronously inside the connecting seat 61, and there will be The spring 632 is compressed, so that the elastic force of the spring 632 can make the anti-slip pad 64 close to the ground, thereby increasing the friction. When the goods are placed on the conveyor roller 2, the conveyor roller 2 can drive the goods to move, and the goods will always move between the two limit seats 43. Since the goods will contact the roller 46 when moving, the goods can drive the roller 46 to rotate. The roller 46 will not hinder the movement of the goods while limiting the position of the goods. When the threaded rod 42 is rotated, the threaded rod 42 can move in a straight line on the surface of the first fixed seat 41, and the threaded rod 42 can drive the roller 46 to move synchronously through the limit seat 43, so the distance between the two limit seats 43 can be adjusted to accommodate goods of different sizes.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
