Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Example 1

As shown in fig. 1 to 3, the continuous fine tuning device for the lifting point of the boom jack is sequentially provided with a supporting mechanism, a lifting mechanism and a continuous fine tuning mechanism from top to bottom,

the supporting mechanism comprises a supporting frame 1 and a steering rod 13, the steering rod 13 is erected on the supporting frame 1 along the vertical direction, and the lower end of the steering rod 13 is assembled and connected with the flow pusher 12;

the lifting mechanism comprises a crane upright post 2, a crane boom 3, a tensile plate 6 and a turnbuckle 10, wherein the top end of the crane upright post 2 is connected with one end of the tensile plate 6 through a connecting rod a4, the other end of the tensile plate 6 is connected with a lifting plate 8 through a connecting rod b7, one end of the crane boom 3 is movably connected with the crane upright post 2, and the other end of the crane boom 3 is fixedly connected with a connecting rod b 7;

the continuous fine adjustment mechanism is set to be a turnbuckle 10, one end of the turnbuckle 10 is connected with the middle upper end of the pull bearing plate 6 through a rotating shaft, the other end of the turnbuckle 10 is connected with the lifting plate 8 through a rotating shaft, the lifting plate 8 is connected with a chain 11 through a chain block 9, and the tail end of the chain 11 is connected with a flow pusher 12.

The middle part of the impeller 12 is provided with a hanger 15, and the hanger 15 is arranged in an inverted V-shaped structure. The structure processing is convenient and fast, and a stable supporting effect is achieved. The top end of the hanger 15 and the chain 11 are provided with a plurality of lifting holes 14 at corresponding positions, and the adjacent lifting holes 14 are arranged horizontally at equal intervals. The lifting positions of the impeller 12 with different impellers (the mass center can be changed when the impellers are different) can be quickly selected through different lifting holes 14, so that the quick installation of the impeller 12 is met.

The bearing and pulling plate 6 is provided with discrete positioning pin holes 5, and the connecting rod a4 is arranged in the positioning pin holes 5 of the bearing and pulling plate 6 through pin shafts. The boom jack adjusts the position of the equipment (via chain 11) by selecting different discrete dowel holes 5 in the carrier plate 6 for smooth installation or lifting of the equipment. Because the positioning pin holes 5 on the bearing plate 6 are discrete, two sizes are different by 100mm in FIG. 1; when the required size is the middle value, the turnbuckle 10 can be used for fine adjustment, and the distance between the chain 11 and the axial direction of the jack is adjusted to be continuous instead of discrete, so that the inclined pulling of the chain 11 can be avoided, and the installation reliability is ensured.

The specific installation and operation process is as follows:

mounting each component according to the structural connection relation, fixing the hanger 15 at the middle part of the outer side of the flow pusher 12 through the bolt 23, connecting the bottom end of the chain 11 connected with the chain block 9 with the lifting hole 14 on the hanger 15, arranging a discrete positioning pin hole 5 on the bearing plate 6, and if the mounting distance of the flow pusher 12 relative to the base is overlarge, hanging the connecting rod a4 in the positioning pin hole 5 on the outer side of the bearing plate 6 (close to the crane upright post 2); if the installation distance of the flow pusher 12 relative to the base is too small, the connecting rod a4 is hung in the positioning pin hole 5 on the inner side of the bearing plate 6 (close to the crane upright post 2);

in the installation process of the flow pusher 12, the crane upright post 2 plays a supporting role, the chain block drives the chain 11 to be conveyed from top to bottom, and the flow pusher 12 is synchronously driven to be conveyed from top to bottom. On the premise of only one lifting point, the water impeller cannot be ensured to be in a horizontal state in air and water, and at the moment, the water impeller can freely move up and down along the guide rod in the air and the water, and particularly, invisible underwater reliable coupling is difficult.

Can find the chain to the optimum distance of guide arm through the experiment in the company, the frictional force that combines impeller 12 and guide arm this moment can realize promoting smoothly and installing impeller 12, but inferior optimum distance is hardly realized when the field installation (for example meet the reinforcing bar when installing chemical bolt, can only trade a position), through adjustment turn buckle 10 this moment, can realize the chain to the optimum distance of guide arm, and then ensure that equipment fixing and promotion are smooth, be favorable to quick location, improve the installation effectiveness greatly.

As shown in fig. 4, an angle adjusting mechanism is further provided, the angle adjusting mechanism comprises a support plate 16, a steering support 18 and a steering adjusting plate 19, the support plate 16 is mounted on the support frame 1, and the support plate 16 is provided with an inner slide way 17 and an outer positioning hole 22 in parallel arrangement; one end of the steering support 18 is connected with the top end of the steering rod 13, the other end of the steering support 18 is connected with a steering adjusting plate 19, and an inner positioning hole 20 and an outer slideway 21 are concentrically arranged on the steering adjusting plate 19; the inner positioning hole 20 and the outer positioning hole 22 are respectively arranged corresponding to the inner slide way 17 and the outer slide way 21 and fixed through bolts 23, and the rotating angle of the steering support 18 is adjusted through screwing the bolts 23.

The inner slide way 17 and the outer slide way 21 are both arranged in a continuous arc-shaped through hole structure. The inner slide way 17 is provided with a continuous arc-shaped through hole, the outer slide way 21 is provided with a plurality of arc-shaped through holes which are arranged in an arc shape at equal intervals to form a structure, and each arc-shaped through hole of the outer slide way 21 corresponds to 3 outer positioning holes 22. The inner slide 17 functions as a main guide rail and the outer slide 21 functions as an auxiliary guide rail. The design mode of inside and outside dual slide can fully guarantee the reliability that bolt 23 locked, and the stability in use is high.

The inner positioning hole 20 and the outer positioning hole 22 are both discrete circular through holes, and adjacent circular through holes are arranged in an arc shape at equal intervals. The inner positioning hole 20 and the outer positioning hole 22 have the same diameter and are matched with the bolt 23. The bolt 23 of being convenient for fixed position of screwing, interior slide 17 and outer slide 21 play the effect of adjusting track simultaneously, it is the arc orbit rotation to turn to regulating plate 19 and turn to support 18 synchronous along interior slide 17 and outer slide 21 that are parallel to each other, relative displacement adjusts fast conveniently, and simultaneously, interior slide 17 and outer slide 21 and corresponding bolt 23 mutually support, play stable limiting displacement, prevent that steering mechanism from because self overweight emergence phenomenon of collapsing, it is controllable to have guaranteed to rotate the orbit accuracy, it is high-efficient to adjust, it is convenient.
