Detailed description of the invention
Understand essence of the present utility model better for convenience of those of ordinary skill in the art, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Figure 1 and Figure 2, special purpose crane produced by a kind of aluminium section bar, comprising: hoist main frame 1, crane span structure 2, hoisting rack 3, sliding machine 4, operator's compartment 5 and clump weight 6.
Wherein, the every platform hoisting crane of the main frame 1 that hoists, sliding machine 4, clump weight 6 configures two covers, and the main frame 1 that hoists is fixed on the girder 21 of crane span structure 2 by support.
As shown in Figure 3, the main frame 1 that hoists is connected to form by physical construction by the support that hoists, motor 11, retarder 12, sprocket wheel 13.Residing for lifting machine, working environment is poor, need Fraquent start in work, stop making motor temperature higher, therefore the utility model select the class of insulation high, starting per hour can be adapted to, stop at YZ type squirrel cage motor within 300 times, thus reduce motor and damage because temperature is higher.
As shown in Figure 4, crane span structure 2 is formed by connecting with bolt primarily of two pieces end carriage 22 and two pieces girder 21, end carriage 22 becomes U-shaped cell body with steel plate bending, girder 21 is then the box-structure become with 4 block plate assembly weldings, and the motor that the end carriage 22 on crane span structure 2 configures, retarder are identical with conventional LDA single-beam crane with car wheel structure can meet actual production requirement.
In practical work process, operating personal drives the motor 11 of the main frame 1 that hoists to move by the control system of operator's compartment 5, motor 11 is connected with the high speed shaft of retarder 12 by a set of brake wheel gear coupling, the mouth of retarder 12 is connected with the main shaft that hoists with a set of sprocket wheel shaft coupling, thus drives two sprocket wheels 13 hoisted on main shaft to rotate.Because hoisting chain one end connects sliding machine 4, the other end connects clump weight 6, and when sprocket wheel 13 rotates, sliding machine 4 and clump weight 6 achieve motion process contrary one on the other.Due to the effect of clump weight 6, the starting current of motor 11 is reduced greatly, therefore motor 11 starting frequently, heat up in stopped process lower, thus effectively protect motor 11.
As shown in Figure 5, the up-and-down movement of sliding machine 4 is that the vertical fixing cart slideway 31 that becomes at the channel-section steel assembly welding of two pieces 18b completes, and the clump weight 6 matched with sliding machine 4 is then do the motion contrary with sliding machine 4 on the counterweight slideway 32 of adjacent edge.
As shown in Figure 6, every platform sliding machine 4 four wheels being parallel to track and four locating wheels perpendicular to track form, and due to traction is the simplex roller chain of two 24A, ensure that sliding machine 4 can pulsation-free up-and-down movement.In addition four pieces of ear seats 41 be connected with suspension hook 42 sliding machine 4 have been welded, suspension hook 42 and ear seat 41 lean on together with hinge, suspension hook has just had certain action radius at work, thus meet in actual production process and require that sliding machine 4 is high on one side, the demand that another side is low, make aluminium section bar can draining fast, save work-hours, improve production efficiency.
The trolley travelling of special purpose crane produced by this aluminium section bar is two overlap independently actuating device, the power frequency of lifting motor is changed by the use of frequency converter, thus change running velocity and the lifting velocity of hoisting crane, hoisting crane is operated steadily, hoists reliably, can also according to the demand of client to production technology, change hook between the running velocity of hoisting crane and lifting velocity, change suspension hook apart from meeting needs of production.
Above detailed description of the invention has been described in detail essence of the present utility model, but can not limit protection domain of the present utility model with this.In every case according to the essence of the utility model, the simple modifications done, modification or equivalent transformation, all drop within claims of the present utility model.
