Description
Technical field
The utility model belongs to the technical field of jacking system, especially a kind of rail mounted elevator with safety device.
Background technology
Elevator uses widely in the industrial production, and its kind is also a lot, and rail mounted elevator is one wherein.Rail mounted elevator relies on chain-driving crane to be risen by weight along fluctuating orbit or fall.In the process of rail mounted elevator operation, run into sometimes circuit control system suddenly the mechanical position of malfunctioning, elevator damage suddenly, chain breakage etc. burst dangerous situation, if now there is no corresponding safety device, be easy to the personal safety jeopardizing operating personal, cause the damage of equipment and product.
Utility model content
The purpose of this utility model is to provide a kind of rail mounted elevator with safety device; by arranging weight guard bar and pressure pin guard bar; occur that control system is malfunctioning at rail mounted elevator, physical construction fault or chain breakage time; weight on pressure pin and pressure pin is blocked within the scope of safe altitude, the safety of protection operating personal and equipment.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of rail mounted elevator with safety device, comprise base and two columns be vertically arranged on base, two root posts are equipped with rail groove along its length, and chain is set in rail groove, this chain is driven by the engine installation in base, the pressure pin be connected with chain is driven to be elevated weight along rail groove, described safety device comprises weight guard bar and pressure pin guard bar, the two ends of weight guard bar are separately fixed on the sidewall of two root posts, and it is parallel with pressure pin, and the lower limit that the position of weight guard bar is elevated higher than pressure pin, pressure pin guard bar is fixedly installed on the opening edge edge of rail groove, and perpendicular to the lifting direction of weight and described pressure pin, the lower limit that the position of pressure pin guard bar is elevated lower than pressure pin.
Preferably, the protection baffle plate of closed orbit channel opening is set in the lower end of described rail groove.
Preferably, the upper surface of described weight guard bar arranges elastic cord breaker, and weight guard bar two ends are respectively equipped with triangular support structure, and triangular support structure is formed by fixedly connecting with weight guard bar and column by its two ends respectively by a strut bar.
Preferably, described triangular support structure be arranged on weight guard bar shaft side or with weight guard bar for axis of symmetry is symmetricly set on the both sides of shaft.
Compared with prior art, the utility model has following beneficial effect:
First, weight guard bar in the utility model be arranged in parallel with the pressure pin of carrying weight, do not affect pressure pin sliding up and down in rail groove, the lower limit that the position of weight guard bar is elevated higher than pressure pin, can ensure that weight guard bar has a safe altitude, and, when elevator breaks down, during weight whereabouts out of control together with pressure pin, on the one hand, weight can be blocked in outside safe altitude by weight guard bar, it is avoided to jeopardize the safety of operating personal, on the other hand, due to when weight whereabouts out of control, impact strength very large, if weight guard bar is arranged on below the lower limit of pressure pin lifting, the weight then fallen can cause serious infringement to elevator, therefore, need weight guard bar to be arranged on more than the lower limit of pressure pin lifting,
Second, pressure pin guard bar in the utility model breaks down at elevator, during pressure pin whereabouts out of control together with weight, pressure pin guard bar can stop the whereabouts of pressure pin, reduces the loss of equipment, and, during pressure pin lifting weight, there is lower limit and upper limit, the lower limit that the position of pressure pin guard bar is elevated lower than pressure pin, therefore, can't hinder the normal operation of elevator;
3rd, the protection baffle plate in the utility model, can prevent foreign material from falling into the stuck chain of rail groove, cause device damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.

Fig. 3 is the constitution diagram of the utility model in weight lower backwardness out of control.
Mark in figure: 1, base, 2, column, 3, rail groove, 4, chain, 5, pressure pin, 6, weight guard bar, 7, pressure pin guard bar, 8, protection baffle plate, 9, strut bar, 10, weight.
Detailed description of the invention
Below in conjunction with accompanying drawing, by detailed description of the invention, the utility model is further described.
As shown in the figure, a kind of rail mounted elevator with safety device, form primarily of base 1 and the column 2 be vertically arranged on base 1, column 2 has two, and along the length direction of column 2, the inner side relative at two root posts 2 arranges rail groove 3, the chain 4 that sprocket wheel drives is provided with in rail groove 3, the sprocket wheel of lower end is connected with the motor output end in base 1, rotated by motor chain drive-belt 4, and drive the pressure pin 5 be connected with chain 4 to be elevated weight along rail groove 3, the lower end of rail groove 3 arranges the protection baffle plate 8 of closed orbit groove 3 opening, described safety device comprises weight guard bar 6 and pressure pin guard bar 7, the two ends of weight guard bar 6 are welded on the sidewall of two root posts 2 respectively, be arranged in parallel with described pressure pin 5, and the lower limit that the position of weight guard bar 6 is elevated higher than pressure pin 6, pressure pin guard bar 7 both ends horizontal is welded on the opening dual-side edge of rail groove 3, and perpendicular to pressure pin 5, the lower limit that the position of pressure pin guard bar 7 is elevated lower than pressure pin 5.
Preferably; weight guard bar 6 adopts cylindrical shaft; and cushion rubber layer is set outside shaft; at the two ends of weight guard bar 6, triangular support structure is set respectively; this triangular support structure is welded on rear on column 1 and weight guard bar 6 formation by a strut bar 9 respectively by its two ends; further, this strut bar is arranged on the below of weight guard bar 6 shaft.
When carrying out lifting weight, two, this elevator be one group with the use of, when breaking down, as: circuit control system is malfunctioning, mechanical breakdown and chain breakage, during weight 10 whereabouts out of control together with pressure pin 5, the weight 10 declined is stopped by weight guard bar 6, stop falling, the personal safety of the operating personnel near elevator can be protected, after weight 10 is stopped, because pressure pin 5 is parallel with weight guard bar 6, so pressure pin 5 can continue to fall, and break through its lower limit, stop by the pressure pin guard bar 7 below lower limit, and then avoid it to cause damage to equipment such as the motors of below.
The protection baffle plate 8 being arranged at rail groove 3 lower end can prevent foreign material from falling into stuck chain 4 in rail groove 3, causes the damage of equipment.
