Abstract

The utility model relates to a roller type stroke switch mounting support seat and a collision block. The support seat has a platform for mounting of a stroke switch, the collision block comprises a collision block support and a collision board fixed at one end of the collision block support, two sides of the platform are fixed with a pair of stop retaining rollers which are parallel, height of the stop retaining rollers is lower than height of the stroke switch, the collision board is an elastic baffle board, two ends of the collision board are respectively hinged with the collision block support through left and right symmetrically-arranged connection rods, and a compression spring is arranged between the collision board and the collision block support. The support seat is provided with the stop retaining rollers for protection, the collision block further employs flexible design, so the collision block has certain tenacity in a vertical direction, damage to the stroke switch is greatly reduced, and stable and reliable operation of equipment are guaranteed.

Description

Rolling wheel type travel switch erection support and collision block

Technical field

The utility model relates to a kind of rolling wheel type travel switch, specifically a kind of rolling wheel type travel switch erection support and collision block.

Background technology

Conventionally the structure of the upper travel switch using of mobile device (as driving, gantry crane) and collision block and operation principle are as shown in Figure 1, the roller 31 that impingement plate 21 pressures of the collision block 2 on being fixed on animal or still life are fixed on the travel switch 3 on still life or animal is during to certain position, promote sensitive switch quick acting, realize and connecting or disjunction control circuit, reach certain control object.The mobile device inertia heavier due to weight such as driving, gantry cranes is large, and when collision block impact stroke switch, impact is large, easily causes travel switch often to damage, and affects the normal operation of equipment.

Summary of the invention

The flimsy problem of travel switch causing greatly in order to solve above-mentioned mobile device inertia; the utility model provides a kind of rolling wheel type travel switch erection support and collision block; can effectively reduce the impulsive force of collision block to travel switch roller, protection travel switch is not damaged.

The utility model is achieved in that the platform on described bearing with an installation travel switch; Described collision block comprises a collision block support and is fixed on the impingement plate of collision block support one end; Described platform both sides are fixed with a pair of limiting block roller being arranged in parallel, and the height of limiting block roller is lower than the roller height of travel switch; Described impingement plate is elastic baffle, and impingement plate two ends are hinged by symmetrically arranged left and right connecting rod and collision block support respectively, makes impingement plate, collision block support and left and right connecting rod form quadric chain; Between impingement plate and collision block support, Compress Spring is housed.

When collision block collision is fixed on the travel switch on bearing, elastic collision plate first with the limiting block roller contact-impact of bearing one side, quadric chain becomes parallelogram by rectangle, discharge after certain energy again with limit switch on travel switch roller contact.Because impingement plate is stopped by limiting block roller, postpone to contact with travel switch, the impulsive force of collision block is applied on limiting block roller, and the impulsive force that travel switch is subject to is greatly reduced, thereby collision block shock can not damage travel switch.

Further, Compress Spring is arranged on left and right connecting rod symmetrical centre, and collision block support is provided with Height Adjustable spring base.By the height of regulating spring seat, can regulate easily the pressure of Compress Spring, make collision block quadric chain keep appropriate rigidity.

As shown from the above technical solution; the utility model bearing arranges limiting block roller in travel switch both sides; travel switch is protected; collision block has also adopted flexible design, and ingenious utilization parallel four-bar linkage is aided with the effect of spring, allows collision block have in vertical direction certain " tough " property; closely be attached on gear roller; can greatly reduce the damage of travel switch, the product of the spacing first-selections of mobile device such as the steady reliability service ，Shi of assurance equipment factory, mine, harbour.And bearing and collision block are reasonable in design, and delicate structure is firm, install simply, long product lifecycle, maintaining is few, practical.

Accompanying drawing explanation

Fig. 1 is existing rolling wheel type travel switch erection support and collision block structural representation;

Fig. 2 is the utility model structural representation;

Fig. 3 is the left view of Fig. 2.

Embodiment

The utility model structure is as shown in Figures 2 and 3:

The platform 13 on bearing 1 with an installation travel switch 3, platform 13 both sides are provided with a pair of limiting block roller 11, limiting block roller 11 is fixed on base 1 by support 12, the height of limiting block roller 11 is slightly lower than roller 31 height of travel switch 3, make collision block 2 by bearing one side limiting block roller top during to the slippage of opposite side limiting block roller top, roller 31 that can impact stroke switch 3 also makes travel switch 3 actions.

Collision block 2 is comprised of impingement plate 21, collision block support 22 and left and right connecting rod 23,24.Described impingement plate 21 is elastic baffle, and impingement plate 21 both sides are hinged by symmetrically arranged left and right connecting

rod

23,24 and collision block support 22 respectively, makes impingement plate 21, collision block support 22 and left and right connecting

rod

23,24 form quadric chain.

Compress Spring 4 is arranged on left and right connecting

rod

23,24 symmetrical centre.Collision block support 22 and impingement plate 21 centre positions are provided with

spring base

41,42, wherein the spring base 41 on collision block support 22 is comprised of nut 412 and screw rod 411, screw rod 411 is fixed on collision block support 22, nut 412 is threaded connection to be fixed on screw rod 411 and forms spring base 41, and adjusting nut 412 positions can regulate the length of Compress Spring 4 between collision block support 22 and impingement plate 21.

Travel switch 3 is fixed on the platform 13 of bearing 1.

Operation principle is as follows:

Under normal circumstances, the quadrangle that left and right connecting

rod

23,24 and collision block support 22 and impingement plate 21 form is because the effect of spring 4 can remain orthogonal, and side is subject to producing distortion after external force.

Collision block 2 is from side switch-oriented 3 motions of gear roller 11, first elastic collision plate 21 contacts with limiting block roller 11 collisions of bearing 1 one sides, after contact, impingement plate 21 moves to opposite side, the quadric chain being comprised of left and right connecting

rod

23,24 and collision block support 22 and impingement plate 21 produces deformation, by rectangle, become parallelogram, contact with the travel switch roller 31 on limit switch 3 again after discharging certain energy.
