Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

Embodiment: a kind of power of determining cable traction apparatus, such as Fig. 1, including rack 1, pull cylinder 2, drive roll 3, motor 4 and Determine force mechanisms 5(such as Fig. 3), pull cylinder 2 is rotatably connected in rack 1, slides connection along the length direction of pull cylinder 2 in rack 1 There is balladeur train 8, motor 4 is fixed on balladeur train 8, and drive roll 3 is rotatably connected on balladeur train 8 by bearing block 81, the output end of motor 4 With drive roll 3 is coaxial is connected, therefore when motor 4 works, can drive drive roll 3 to rotate.Operator can move balladeur train 8 and will lead Dynamic roller 3 is inserted into pull cylinder 2 and is coaxially disposed with pull cylinder 2, offers location hole 83 in rack 1 at this time, is equipped on balladeur train 8 Positioning pin 82, positioning pin 82, which is threaded through in location hole 83, can quickly fix position of the balladeur train 8 in rack 1.2 He of pull cylinder It is equipped between drive roll 3 and determines force mechanisms 5, when so that drive roll 3 rotating, can be not more than under the thrust of certain force and drive pull cylinder 2 rotations, in order to the winding cable 9 of safety.

Such as Fig. 2 and Fig. 3, determines force mechanisms 5 and include the push plate 51 being fixedly connected on 3 outer wall of drive roll, be hinged on pull cylinder 2 Baffle 52 and extension spring 53 on inner wall are equipped with pull ring 531 in pull cylinder 2 and drive roll 3, and pull ring 531 is along pull cylinder 2 It is equipped with the length direction of drive roll 3 multiple, the both ends of extension spring 53 are hung on the pull ring of pull cylinder 2 and drive roll 3 respectively On 531.When drive roll 3 rotates, side of the push plate 51 towards baffle 52 towards extension spring 53 on drive roll 3 is contradicted and right Baffle 52 apply a thrust, at this time extension spring 53 be stretched and limit baffle 52 rotation, so as to drive pull cylinder 2 with Drive roll 3 rotate.If tractive force suffered by cable 9 is greater than the pulling force of extension spring 53 in pull cylinder 2, push plate 51 can be contradicted Baffle 52 rotate and cross baffle 52, push plate at this time 51 will dally in pull cylinder 2, thus no longer drive 2 turns of pull cylinder Dynamic, to reduce, 9 stress of cable is excessive and leads to the possibility damaged.Operator can adjust by adjusting the quantity of extension spring 53 The maximum thrust between push plate 51 and baffle 52 is saved, so as to adjust cable 9(such as Fig. 1 in pull cylinder 2) maximum drawbar pull.

Such as Fig. 2 and Fig. 3, determine there are two force mechanisms 5 set along the diametrical direction of 3 cross section of drive roll, two are determined 5 edge of force mechanisms The diametrical direction of 3 cross section of drive roll is arranged, thus when drive roll 3 rotates, it can be along the two of 2 cross-sectional diameter direction of pull cylinder End applies thrust to pull cylinder 2, consequently facilitating pull cylinder 2 rotates, also improves the rotational stability of pull cylinder 2.

If the side of Fig. 2 and Fig. 3, push plate 51 towards baffle 52 are set as fillet, consequently facilitating push plate 51 it is smooth cross gear Plate 52.Drive roll 3 is equipped with the deep floor 7 of triangle in push plate 51 away from the side of baffle 52, and deep floor 7 is along push plate 51 Equal spacing in length direction is equipped with multiple, to substantially increase the structural strength of push plate 51, reduces push plate 51 away from baffle The curved possibility in 52 directions.

Such as Fig. 2 and Fig. 3, baffle 52 is equipped with pressure sensor 54 towards the side of push plate 51, and rack 1 is equipped with alarm 55(such as Fig. 1), when push plate 51 is separated with 52 phase of baffle, pressure sensor 54 is no longer pressurized, and pressure sensor 54 controls at this time Alarm 55 alarm, thus prompt operator check cable 9(such as Fig. 1) or adjustment motor 4 revolving speed, in order to adjust cable 9 Tractive force be lower than preset value, continue to complete the traction work of cable 9.

Such as Fig. 2 and Fig. 3, the one end of pull cylinder 2 along its length is equipped with mark power ruler 6, and baffle 52 is equipped with directional beacon power ruler 6 Direction line 61, operator can intuitively observe the deflection angle of baffle 52 by marking power ruler 6, further according to extension spring 53 Quantity rapidly calculate thrust suffered by baffle 52, so that cable 9(such as Fig. 1 is learnt in quicklook) tractive force, so as to Corresponding adjustment is made in operator.

Operating process: operator according to the maximum drawbar pull for being determined cable 9 by the case where winding cable 9, then exists first The extension spring 53 of corresponding number is hung on the pull ring 531 of pull cylinder 2 and drive roll 3, pushes balladeur train 8 towards pull cylinder 2 at this time Until drive roll 3 is worn in pull cylinder 2, then balladeur train 8 is fixed in rack 1 by positioning pin 82, starts motor at this time 4, motor 4 drives drive roll 3 to rotate, and the push plate 51 on drive roll 3 is just inconsistent with baffle 52, to pass through 52 pairs of baffle tractions Cylinder 2 applies a thrust, and then pull cylinder 2 is driven to rotate, and extension spring 53 is stretched at this time；If in pull cylinder 2 suffered by cable 9 Tractive force be greater than extension spring 53 pulling force when, push plate 51 can contradict baffle 52 rotate and cross baffle 52, push plate at this time 51 will dally in pull cylinder 2, so that no longer driving pull cylinder 2 rotates, to reduce, 9 stress of cable is excessive and leads to damage May, pressure sensor 54 is not pressurized at this time, just controls alarm 55 and sounds an alarm.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
