It should be noted that various changes and modifications can be made by one skilled in the art without departing from the spirit of the invention. These all belong to the protection scope of the present invention.

Example 1

An unpowered conveying device for small equipment in flow line production is structurally shown in figure 1, and mainly comprises a pulley block 1, a balancing weight 2, a support frame 3, a guide rail assembly 5, a supporting plate assembly 6 and the like, so that unpowered conveying is realized.

In this embodiment, the pulley block 1 used is composed of four fixed pulleys 11 and four movable pulleys 12 disposed below the fixed pulleys 11, and the fixed pulleys 11 and the movable pulleys 12 are connected to each other by the wire rope 3. In order to avoid interference of the steel wire rope, the diameters of the pulleys are different and are arranged in sequence from large to small, specifically, the diameters of the four fixed pulleys 11 are gradually reduced from top to bottom, and correspondingly, the diameters of the four movable pulleys 12 are gradually increased from top to bottom. Because the conveying stroke is long, the movable pulley principle (labor and cost saving stroke) is adopted to meet the requirements of stroke and gliding labor saving. The pulley block 1 formed by four groups of fixed pulleys 11 and movable pulleys 12 reaches 8 times of stroke (S is 8h), and the load slips easily (F is 1/8G).

The balancing weight 2 that uses provides the pulling force demand that the layer board returned journey, be connected with a movable pulley 12 that sets up at the below, a return journey for layer board subassembly 6, rely on balancing weight 2 dead weight to pull back layer board subassembly 6, the weight of balancing weight 2 can be according to actual speed requirement, the frictional force size on the guide rail assembly increases and decreases, need can guarantee to pull back layer board subassembly 6, in addition, balancing weight 2 through setting up a basis weight, make layer board subassembly 6 speed can be controlled when following guide rail subassembly 5 cunning, even make layer board subassembly 6 reach the speed when terminal point also be 0 through detailed calculation, can not like the speed that is carried the gliding of thing can increase gradually in the unpowered conveyor among the prior art, because the impact force is great leads to life to shorten when arriving the terminal point.

Guide rail set spare 5 comprises two parallel arrangement's aluminum alloy guide rail, is the slope setting, supports through support frame 3, and guide rail set spare 5's gradient needs to guarantee to lean on the dead weight to slide down along guide rail set spare 5 after having put into pedal power test equipment on layer board subassembly 6. The side of the guide rail assembly 5 close to the pulley block 1 is higher, the side is also the starting point of conveying, and the position of the conveying end point on the other side is lower. The inclination angle of the guide rail assembly 5 can be adjusted according to the actual gliding speed requirement. The adjustment of the above-mentioned inclination angle is realized by adjusting the support frame 4. The supporting frame 4 used in the embodiment is a bar rack, a plurality of supporting frames are arranged from the starting point to the end point along the lower part of the guide rail assembly 5, the height of each bar rack can be adjusted, one side close to the pulley block is higher, the end point of the other side is lower, and the height of the bar rack can be adjusted according to needs so as to adjust the inclination of the guide rail assembly, so that the use is more flexible.

The pallet assembly 6 is placed on the rail assembly 5, slides along the rail assembly 5, and the pallet assembly 6 is connected with the movable end of the wire rope 3. The pallet assembly 6 used has a structure as shown in fig. 2, which is used to place and convey the pedal force device, is provided at the upper surface thereof with a plurality of positioning blocks 61 for positioning the pedal force device to prevent it from falling down during sliding, and is provided at the lower surface thereof with a plurality of wheels 62 to be able to slide along the guide rails.

Besides, this embodiment still is equipped with buffering subassembly 7 at one side that assembly pulley 1 is close to guide rail set spare 5 and the terminal point position of guide rail set spare 5, avoids equipment to cause the damage at the gliding process and by the impact shock that the in-process that the balancing weight was pulled back to use buffering subassembly 7 can also play the effect that makes layer board subassembly 6 stop motion. Cushioning assemblies 7 that may be used include rubber blocks, foam pads, or gas springs, among others. The damping assemblies 7 used in this embodiment are 2 sets of gas springs.

The utility model discloses when using, initial condition, empty layer board subassembly 6 stops in the blowing position, and this station operative employee places the pedal power equipment that the test has finished on layer board subassembly 6, and layer board subassembly 6 begins the gliding together with equipment is automatic under the effect of gravity at once, stops until guide rail assembly 5's terminal point and the buffering subassembly 7 of striking below. This station operative employee gets pedal power equipment and puts into the product car and tests in getting the material position, and because the equipment has been taken away and cause the load to lighten this moment, empty layer board subassembly 6 is drawn back to the initial position and strikes the buffering subassembly 7 of top through assembly pulley 1 by balancing weight 2 and stops, accomplishes whole duty cycle.

Example 2

An unpowered conveying device for small equipment in flow line production is basically the same as that in embodiment 1, except that only one fixed pulley and one movable pulley are required to form a pulley block due to the short conveying length in the embodiment.

Example 3

An unpowered conveying device for small equipment in flow line production is substantially the same in structure as embodiment 1, except that a pulley block is formed by three fixed pulleys and three movable pulleys, and a rubber pad is adopted to replace a gas spring as a buffer assembly.
