Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
Referring to fig. 1-4, fig. 1 is a schematic structural diagram of a specific embodiment of a special lifting device provided in the present invention; fig. 2-4 are projection views in each plane of the spreader of fig. 1.
In a specific embodiment, the utility model provides a special lifting device is used for railway coil of strip transportation seat frame to can cooperate present horizontal coil of strip clamp to realize automatic picking and hanging the steel seat frame in term, and realize not having after the steel seat frame of hoisting to collide with and steadily hang out, finally realize the economic input that no personnel participated in the operation and bring, optimize the operation flow, eliminate the unsafe factor that exists in the operation.
The special lifting appliance comprises a clamp and a lifting appliance body 100, wherein the clamp comprises two clamping arms which are driven by a power part to be connected in an opening and closing manner; the hanger body 100 is mounted on at least one of the clamping arms and is fixedly connected with the clamping arm, and a fork ruler 200 is arranged at one end of the hanger body 100, which is far away from the clamping arm; the hanger body 100 is driven by the clamp to approach or separate from the steel coil conveying seat, so that the fork ruler 200 can be inserted into or separated from the preset position of the steel coil conveying seat.
The clamp is specifically an existing horizontal rolling clamp, the structure and the working principle of the horizontal rolling clamp are the same as those of the prior art, and the detailed description is omitted here.
Further, a snap ring is further included, as shown in fig. 5-8, one end of the snap ring is fixedly connected to the spreader body 100, and the other end thereof is fixedly connected to the clamping arm. In the manufacturing process of the lifting appliance, the snap ring is fixed below the clamping arm of the horizontal coil type electric clamp in a hard connection mode (for example, 10.9-grade screws or welding and the like), the fork ruler 200 is inserted into a V-shaped groove triangular support plate of the steel coil conveying seat through the opening of the electric clamp, the steel seat frame is lifted out by using a gantry crane, and automatic unhooking is realized in a clamping mode of the clamp.
In order to improve the structural stability and adapt to the structure of the steel coil conveying seat, the hanger body 100 includes a first hanger arm 101, a second hanger arm 102 and a connecting arm 103, the fork ruler 200 is fixedly connected to the connecting arm 103, and the clasp is fixedly connected to the first hanger arm 101 and/or the second hanger arm 102.
The first boom 101, the second boom 102 and the connecting arm 103 form a triangular structure in order to have a good structural strength in a space as small as possible.
The two fork rulers 200 are respectively arranged at two bottom corners of the triangular structure, and the snap ring 300 is arranged at the top corner of the triangular structure.
The lifting appliance mainly bears shearing force, and the V-shaped groove triangular support of the steel coil conveying seat is 150mm long, so that the length of the fork ruler 200 is about 200 mm. The fork ruler 200 and the main load surface adopt a through type double-sided welding technology, so that the fork ruler 200 is subjected to lever prying force to offset partial shearing force, the stress intensity is increased, and the lifting appliance is subjected to upward pulling force of the lifting hook, the weight of the steel coil conveying seat and downward acting force of the self weight of the lifting appliance. The force of the steel coil conveying seat acts on the center, and the gravity of the lifting appliance acts on the gravity center of the lifting appliance. The section of the vertical section of the lifting appliance is mainly stressed by tension, the tensile stress is equal to the gravity of the lifting appliance divided by the sectional area, and the yield strength of the lifting appliance is divided by the tensile stress, namely the safety coefficient 7.

Further, the length of the first boom 101 is larger than the length of the second boom 102. For example, the second boom 102 near one side of the cab has a length of 800mm, the first boom 101 on the opposite side has a length of 950mm, and the two arms differ by 150 mm. A micro-inclined hoisting framework is constructed through the uneven-equation hoisting arms, so that stable hoisting and stacking of the steel seat frame without collision are realized.
In order to bear a large hoisting force and avoid overturning, two of the hanger bodies 100 are provided, and the two hanger bodies 100 are respectively and correspondingly mounted on the clamping arms one by one. In particular, when the steel seat frame is used, one open wagon often uses two steel bases (namely, a steel coil conveying seat) or three steel bases, and a 60t universal open wagon, a 61t universal open wagon or a 70t universal open wagon is selected according to the loading weight. As the longitudinal displacement and the overturn of the train can not occur in the running process under the load state and the additional reinforcement is not carried out on the steel coil base, the clamping block welded on the side plate of the steel seat frame abuts against the side wall reinforcing inclined iron of the train, in order to avoid scraping and rubbing the side wall to cause damage in the hoisting operation, the hoisting tool is designed to be an uneven-type hoisting tool with an uneven hoisting arm, the self weight of the steel seat frame is 0.685t, the gravity center is 115mm away from the train bottom plate, the width of the V-shaped groove bottom plate is 445mm, and the thickness of the.
In the above specific embodiment, in the process of hoisting the steel coil conveying seat, the hanger body 100 is first fixed on the clamping arm of the clamp, then the hanger is lowered into the carriage, and the clamp is clamped to insert the fork gauge 200 on the hanger body 100 into the steel coil conveying seat; loosening the clamp to enable the lifting appliance to be firmly hung on the conveying seat; and lifting out of the carriage, then placing the conveying seat at a specified position, and finishing an operation process after the clamping clamp is hooked out. Like this, realized the automation of coil of strip transport seat through the cooperation of hoist body 100 and clamp and hooked and unhook, avoided artifical unhook the working strength that causes big, the operation danger degree is high and work efficiency hangs down the scheduling problem to improve work efficiency, reduced the operation danger, reduced working strength. Moreover, production practice proves that the average cost saving is monthly wages and labor saving is 3000 multiplied by 4 multiplied by 12 multiplied by 144000 yuan each year, and the average saving time of each row is base number multiplied by (average operation time before improvement-average operation time after improvement) 100 multiplied by (8-3) multiplied by 500 minutes, so that the potential safety hazards in the operation such as crushing and falling injury are completely eliminated.
