Along with the development of modern wharf freight transportation, the weight of goods is gradually increased, and in order to improve the lifting capacity of a rail crane, the weight of a lifting mechanism of the rail crane is also gradually increased, which brings a challenge to the existing bearing capacity of the wharf. In order to solve the problem that the rated bearing wheel pressure in the unit range of the wharf is not enough to bear the instantaneous overload wheel pressure of the crane, the unit wheel pressure of the crane is reduced by increasing the total width of a crane cart walking mechanism or increasing the bearing capacity of the wharf in part of the wharf. However, in a part of old docks, a dock rail cannot be changed at will, the lifting capacity of the whole crane is greatly limited by the arrangement space of a cart walking mechanism scheme, and the large crane has the contradiction of large wheel pressure and low dock bearing capacity, so that the lifting capacity of the rail crane cannot be improved later. In order to solve the problem, the utility model provides a partial pressure mechanism is assisted to hoist.
The following first describes a crane auxiliary pressure-dividing mechanism according to the present invention with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model provides a pressure divider is assisted to hoist constructs, include: bracket 100, hydraulic ram 200, trolley assembly 300, and lower pin shaft assembly 400. The support 100 is used for being connected with a balance beam of the crane; one end of the hydraulic oil cylinder 200 is connected with the bracket, the other end of the hydraulic oil cylinder is provided with a first pin shaft connecting plate 201 in a telescopic manner, and a first through hole is formed in the first pin shaft connecting plate 201; the trolley assembly 300 is inserted into the first through hole through the lower pin shaft assembly 400 to be hinged with the hydraulic cylinder 200.
Specifically, the bracket 100 is disposed below the crane and fixedly connected to a lower beam of a doorframe below the crane, and the bracket 100 is formed in an inverted triangle shape or an inverted trapezoid shape. In a preferred embodiment of the present invention, the support 100 is an inverted trapezoid, which has a stable structure, thereby improving the stability of the support 100 and stably suspending the trolley assembly 300 below. One end of the hydraulic cylinder 200 is fixedly connected with the bracket 100, and the other end thereof can be extended and contracted to form a first pin connecting plate 201. The trolley assembly 300 of the crane auxiliary pressure-dividing mechanism is a driven trolley set for following a driving trolley set (not shown) to move on a track; the lower pin shaft assembly 400 is respectively inserted into the first through hole of the first pin shaft 420 and the second through hole of the connecting plate 301. Thus, under normal operating conditions, hydraulic ram 200 may suspend trolley assembly 300 below carriage 100 at a distance of 20-30 centimeters from the dock track via lower pin shaft assembly 400. At the moment, the crane walks through the driving trolley group, and the driven trolley group is not required to be driven, so that the friction force between the driven trolley group and the wharf track is overcome, and the running speed of the driving trolley group can be effectively improved. When the wheel pressure of the crane exceeds the bearing wheel pressure of the wharf and needs to be dispersed through the trolley component 300, the hydraulic oil cylinder 200 can be started to push the first pin shaft connecting plate 201 to drive the trolley component 300 to descend, and the trolley component 300 is supported on the wharf rail. At this time, a part of load borne by the crane is transmitted to the wharf rail through the trolley assembly 300, and the trolley assembly 300 and the driving trolley group share wheel pressure, so that the wheel pressure borne by the wharf rail surface is reduced, and the service life of the travelling mechanism is effectively prolonged.
As shown in fig. 1 and 2, in an embodiment of the present invention, the bracket 100 includes: two first limiting plates 110. Two first limiting plates 110 are symmetrically arranged below the support 100, the two first limiting plates 110 are respectively provided with a waist-shaped through hole 111, the long edge of the waist-shaped through hole 111 is perpendicular to the horizontal ground, and the two first limiting plates 110 penetrate through the waist-shaped through hole 111 and are arranged on the lower pin shaft assembly 400.
Specifically, the bracket 100 is connected to the carriage assembly 300 by the hydraulic cylinder 200, and the first pin connecting plate 201 of the hydraulic cylinder 200 is rotatably connected to the connecting plate 301 of the carriage assembly 300 by the lower pin assembly 400, so that the carriage assembly 300 is displaced by inertia when the crane travels, and therefore, it is necessary to limit the displacement. Waist-shaped through holes 111 are respectively formed in the two limiting plates and penetrate through the waist-shaped through holes 111 on the lower pin shaft assembly 400, so that when the hydraulic oil cylinder 200 pushes the trolley assembly 300, the trolley assembly 300 always moves along the length direction of the waist-shaped through holes 111, wherein the length direction is perpendicular to the horizontal ground. Therefore, the problem of safety accidents caused by deviation of the trolley assembly 300 due to inertia when the crane travels is avoided, and the safety of equipment is effectively improved.

Accordingly, the bracket 100 and the hydraulic cylinder 200 may be rotatably coupled by the upper pin assembly 500, thereby effectively dispersing the lateral stress. Therefore, the metal fatigue occurrence probability is effectively reduced, and the safety performance is improved. More specifically, thereby go up the pin shaft subassembly 500 and wear to establish respectively in two second limiting plates 120 and second pin connecting plate 202 and connect hydraulic cylinder 200 in support 100 below, when the hoist wheel pressure surpassed pier bearing wheel pressure, when needing to disperse the wheel pressure through platform truck subassembly 300, can start hydraulic cylinder 200 and promote first pin connecting plate 201 and drive platform truck subassembly 300 and descend to support platform truck subassembly 300 and hold on the pier track. At this time, the hydraulic cylinder 200 may transmit a relative force equal to a fixed load applied to the trolley assembly 300 upward, so that the hydraulic cylinder 200 is stressed in a vertical direction in a balanced manner, and the stability of the trolley assembly 300 below the hydraulic cylinder 200 during operation is effectively improved. Thereby, the safety performance is further improved.

Specifically, the trolley assembly 300 has a large mass, and if the hydraulic cylinder 200 is rigidly connected to the trolley assembly 300, the connection will shake due to the inertia of the trolley assembly 300 to cause metal fatigue, and then break, thereby resulting in potential safety hazards. Therefore, the hydraulic oil cylinder 200 and the trolley assembly 300 are rotatably connected through the lower pin shaft assembly 400, so that the stress can be effectively dispersed, the probability of metal fatigue is reduced, and the safety performance is improved. More specifically, the two first positioning shaft sleeves 410 are clamped in the waist-shaped through hole 111 through the first fixing portion arranged at the end departing from the first pin connecting plate 201, and the two first positioning shaft sleeves 410 are not in contact with each other, so that the first pins 420 penetrating through the two first positioning shaft sleeves 410 can be directly in contact with the inner wall of the first through hole.
