In recent years, due to developing rapidly of the industry such as steel plant, shipbuilding yard, the demand of magnetic chuck hoisting crane also constantly increases, and its specification and pattern are also varied.Magnetic chuck hoisting crane is widely used in the assembling of manufacture, large-scale precision equipment, and its handling limited space, lift heavy are large, Hoisting Position requires accurately, careless slightly, and goods will be caused to disintegrate or damage himself structure.And along with the increase of suspending steel wire rope length, the load of hoisting crane will take a long time on quick position, have impact on production efficiency, therefore, be necessary to study how fast and stable lift heavy, and design its control system, effectively increase work efficiency and safety.
Wherein, crane in bridge type be crossbearer in workshop, warehouse and overhead, stock ground carry out the weight-lifting equipment of material handling.Two ends due to it are seated on tall and big concrete column or metallic support, and shape is like bridge.The crane span structure of crane in bridge type along be laid on both sides overhead on track longitudinally run, the space handling material below crane span structure can be made full use of, not by the obstruction of wayside equipment.It is a kind of elevator machinery that range of use is the widest, quantity is maximum.
But, in operation process, due to operating personal misoperation, or careless and inadvertent, again or brake failure, easily there is the situations such as crane span structure collision, derailing, there is larger potential safety hazard.
Summary of the invention
The mobile stop gear that the purpose of this utility model is to overcome weak point of the prior art and provides a kind of hoisting crane, this mechanism structure is simple, the situations such as crane span structure collision or derailing effectively can be avoided to occur, improve the safety performance of equipment use, ensure that the normal use of equipment.
For achieving the above object, the utility model adopts following technical scheme:
A kind of mobile stop gear of hoisting crane, comprise overhead and crane span structure, these overhead both sides are provided with slide rail, described crane span structure two ends are respectively equipped with column, respectively the opposite exterior lateral sides of this column is connected with a sliding unit respectively by a connection piece, and respectively this sliding unit slides and is connected on overhead corresponding slide rail, and respectively these sliding unit two ends are at least provided with two buffer part respectively, each slide rail two ends overhead on be respectively equipped with detent, respectively this buffer part avoids the sliding unit excess of stroke for coordinating detent.
Describedly overheadly comprise roof beam structure and be located at the pillar of each angle of roof beam structure respectively, each pillar is mutually vertical with this roof beam structure, and this roof beam structure is made up of four interconnective crossbeams, and each crossbeam is mutually vertical, and described two slide rails are respectively on located therein two crossbeams be parallel to each other.
Described each sliding unit is made up of a wheel carrier and the pulley of being located at wheel carrier two ends respectively, respectively this sliding unit is slidably connected on corresponding slide rail by pulley, described each buffer part is located at the two ends of corresponding wheel carrier respectively, and each buffer part stretches out corresponding wheel carrier towards one end of detent, wherein, each buffer part is an energy disperser.
Described each detent all by a support respectively at corresponding slide rail two ends overhead on, respectively the rational height of this detent is consistent with the rational height of corresponding buffer part.
The beneficial effects of the utility model are: it matches with detent by means of only buffer part, when the buffer part of sliding unit touches detent, buffer part is triggered to detent, in time crane span structure is braked by detent, and then effectively avoid the situations such as crane span structure collision or derailing to occur, improve the safety performance of equipment use, ensure that the normal use of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in Fig. 1 A place without the close-up schematic view of buffer part state.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail:
As shown in Figure 1-2, the utility model, about a kind of mobile stop gear of hoisting crane, comprises overhead 1 and crane span structure 2, and these overhead 1 both sides are provided with slide rail 11, and this crane span structure 2 is provided with a dolly 21, and this dolly 21 is for coupling hook or magnetic chuck.
As shown in Figure 1, overhead 1 comprises roof beam structure 12 and is located at the pillar 13 of each angle of roof beam structure 12 respectively, each pillar 13 is mutually vertical with this roof beam structure 12, this roof beam structure 12 is made up of four interconnective crossbeams 121, each crossbeam 121 is mutually vertical, and two slide rails 11 are respectively on located therein two crossbeams be parallel to each other 121.
As shown in Figure 1, crane span structure 2 two ends are respectively equipped with column, respectively the opposite exterior lateral sides of this column is connected with a sliding unit 3 respectively by a connection piece, respectively this sliding unit 3 slides and is connected on overhead 1 corresponding slide rail 11 on one side, respectively these sliding unit 3 two ends are at least provided with two buffer part 31 respectively, on overhead 1 of each slide rail 11 two ends, be respectively equipped with detent 14, respectively this buffer part 31 avoids sliding unit 3 excess of stroke for coordinating detent 14.
As shown in Figure 1-2, each sliding unit 3 is made up of a wheel carrier 32 and the pulley 33 of being located at wheel carrier 32 two ends respectively, respectively this sliding unit 3 is slidably connected on corresponding slide rail 11 by pulley 33, each buffer part 31 is located at the two ends of corresponding wheel carrier 32 respectively, and each buffer part 31 stretches out corresponding wheel carrier 32 towards one end of detent 14, wherein, each buffer part 31 is an energy disperser.
As shown in Figure 1, each detent 14 all by a support 15 respectively on overhead 1 of corresponding slide rail 11 two ends, respectively the rational height of this detent 14 is consistent with the rational height of corresponding buffer part 31, and wherein, each detent 14 is a brake switch.
In actual use, when crane span structure 2 is for being braked in time, buffer part 31 can continue feeding because of sliding unit 3, and touches detent 14, and now, detent 14 cuts off the power supply of sliding unit 3 in time, brakes the crane span structure 2 be connected with sliding unit 3.
The above is only to preferred embodiment of the present utility model; not scope of the present utility model is limited; therefore under the prerequisite not departing from the utility model design spirit; the equivalence change that the common engineering staff in this area do structure described in the utility model, feature and principle or decoration, all should fall in protection domain that the utility model applies for a patent.
