2. the utility model brakes to mobile roof support and steamboat respectively simultaneously at glancing impact, can guarantee safe and reliable, and in whole use braking brake at any time.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an assembling scheme drawing of the present utility model.
Wherein: 1. vehicle frame; 2. axletree; 3. mobile roof support; 4. steamboat; 5. brake support; 6. brake bowl; 7. locating dowel pin; 8. spring; 9. knock hole; 10. push pipe; 11. slotted hole; 12. end face tooth; 13. side tooth; 14. extension spring; 15. brake cable; 16. brake handle; 17. anchor clamps; 18. handle; 19. steel wire; 20. sleeve pipe; 21. catch.
Embodiment: as Fig. 1, shown in Figure 2, a kind of brake equipment of cart for travelling up or down stairs, comprise vehicle frame [1], axletree [2] on the vehicle frame [1], the mobile roof support [3] of axletree [2] two side ends, be located at the steamboat [4] of mobile roof support [3] termination, the side that is positioned at mobile roof support [3] on the described axletree [2] is with the brake support [5] identical with mobile roof support [3] shape, the termination of brake support [5] is provided with braking bowl [6], braking bowl [6] is aimed at steamboat [4], brake support [5] is provided with locating dowel pin [7], be with on the locating dowel pin [7] in the knock hole [9] on spring [8] and the insertion mobile roof support [3], the side of the upper brake support of described axletree [2] [5] is with push pipe [10], the side of push pipe [10] is provided with slotted hole [11], vehicle frame [1] just is stuck in the slotted hole [11] with the coupling end of axletree [2], one end of described push pipe [10] is provided with end face tooth [12], end face tooth [12] is aimed at the side tooth [13] that brake support [5] side is provided with, being provided with extension spring [14] in the push pipe [10] makes push pipe [10] press to brake support [5], also be connected with the brake cable [15] of holding push pipe [10] on the push pipe [10], brake cable [15] is connected with brake handle [16] on being fixed on vehicle frame [1]; Described brake [16] by clamp fitting on vehicle frame [1] anchor clamps [17] and clamped by anchor clamps [17] and pivotally attached handle [18] is formed; Steel wire [19] in the described brake cable [15] is connected on push pipe [10] and the handle [18], and the sleeve pipe [20] of brake cable [15] then is separately fixed at and is arranged on axletree [2] the middle catch [21] and anchor clamps [17].During use, brake support [5] is inserted in the knock hole [9] on the mobile roof support [3] by thereon locating dowel pin [7], therefore, brake support [5] and then mobile roof support [3] rotates together, and the spring [8] that is overlapped on the locating dowel pin [7] ejects brake support [5], and and form between the mobile roof support [3] at interval, even braking bowl [6] leaves steamboat [4], do not influence the rotation of steamboat [4]; Glancing impact, hold brake crank [18], brake steel wire [19] unclamps push pipe [10], push pipe [10] is gone up mobile under the effect of extension spring [14] at axletree [2], compress brake support [5], side tooth [13] interlock on end face tooth [12] on the push pipe [10] and the brake support [5], make push pipe [10] with brake support [5] interlock, and can not rotate because snapping in of vehicle frame [1] arranged in the slotted hole [11] on the push pipe [10], so that this moment brake support [5] can not rotate, still under the effect of the extension spring [14] in push pipe [10], carve the elastic force of having obeyed the spring [8] on the locating dowel pin [7], make brake support [5] also compress mobile roof support [3], at this moment, braking bowl [6] has also compressed steamboat [4], steamboat [4] can not be rotated, thereby up hill and dale cart for travelling up or down stairs has been checked.
