The small-sized gantry crane apparatus function of the utility model is achieved in that
Like Fig. 1, shown in 2, this small-sized gantry crane device is a truss structure, has multiple different types of shaped steel to cooperate lifting means to assemble voluntarily and is welded, and positive facade and back elevation are the identical truss of two Pin and connect into the square bar structure through shaped steel.The as can beappreciated from fig. 2 facade face truss 9 of the positive facade of square bar structure and back elevation both sides, said frame roof is provided with service platform 11, and said base of frame is provided with base plate; Base plate is provided with motor 2 and counterweight 4, is provided with steel I-beam in the middle of the service platform 11 following frame roof, and said steel I-beam one side is provided with motor hoist 3; The angular position up and down of the every truss structure of front-back is equipped with rail supported 7, and steel I-beam is No. 14 I-beam sections, and rail supported is No. 10 channel-section steels; Steel type is the Q235 type; The leg of support node is of a size of 5mm, and fusion length is a full weld, and welding rod adopts the E50 type.Every truss structure two side bottoms of front-back are provided with track 1, and track 1 is welded to form at inner corner trim place and No. 18 screw-thread steels by the angle steel of 60mm * 60mm * 5mm.Fwd one truss structure one middle side part is provided with switch box 5, and is electrically connected with motor hoist 3 and motor 2, and a truss structure one side of back is provided with maintenance cat ladder 6, and roller 8 is arranged on the foot of every truss structure.
Said counterweight 4 is a concrete prefabricated element, confirms its weight by calculating; Said switch box 5 provides 380v voltage; Said maintenance cat ladder 6 is formed by No. 16 screw-thread steel welding productions.
Said roller 8 is the steel wheel of band groove, and the gear on the motor shaft of the gear that the roller bearing of roller 8 carries and motor 2 is meshed.Also can link to each other with motor 2 through jack.
For reaching the requirement of mechanization of building operation and safety construction, this small-sized gantry crane device has been taked following method:
(1) gantry crane is whole moves: adopt the totally-enclosed cooling mouse light type three phase asynchronous motor of Y series to link to each other through jack with the roller of gantry crane, reach the whole purpose that moves.
(2) template put forward fortune: adopting model is the motor hoist of TSJ-A, can be through track cross level transportation template, also can be through the hoisting equipment vertical transport template of self.
(3) safety measure: each motor device all has quick-fried stop device, and when taking place in the work progress to have a power failure suddenly, motor can be automatically locked on the track of oneself, avoids because inertia causes unnecessary harm.At a unsettled side setting operation platform of bridge, around the service platform fence is set, in addition for operating personal provides safe job platform.
The small-sized gantry crane device integral body of the utility model is truss structure; Positive facade and back elevation are the identical truss of two Pin and connect into the square bar structure through shaped steel; The top is provided with the steel I-beam of the moving gig operation of power supply, and the bottom is provided with the angle steel track that supplies small-sized gantry crane device operation.Equipment package is accomplished the overall process that template is put forward fortune through power motor and operating handle.
Personnel's configuration
In order to make the maximum work efficiency of small-sized gantry crane device performance need be equipped with rational constructing operation personnel, take all factors into consideration the characteristics of main road, beach crash barrier construction, configuration personnel situation is following:
Template fettler 2 people are responsible for the polishing of template and the cleaning work of small-sized gantry crane device operation road;
Machine behaviour worker 1 people appoints group leader, the operation that takes charge and construct and operate small-sized gantry crane device;
Carpenter 4 people, the level of being responsible for inner and outer template connects;
1 of electric welder, the seam slab muscle welding of being responsible for rising.
Safety inspection work before using:
, gantry crane at first should check the quality problems of motor and lifting means before using.For the mechanical equipment that dispatches from the factory, not only to satisfy industry requirement, also should National standard, product incomplete for certificate and that do not meet standard-required must not be used in the construction without exception.
At first, counterweight inspection.This is a condition precedent of guaranteeing the gantry crane safety traffic.The principle of counterweight inspection should be to guarantee that in the biggest lifting capacity and maximum lifting distance gantry crane does not topple; Because the gantry crane deadweight is far longer than the weight of template; Toppling under the sagging moment effect can not take place; Counterweight can not calculated, and only needs to calculate the counterweight under the hogging moment, and the formula that then counterweight is calculated under the hogging moment effect is:
ε×F×y≤(x-0.5a)×G
In the formula: the maximum guardrail template hoisting capacity of F, gantry crane; G, selected concrete counterweight amount; Distance between x, the track; Y, outer side track are apart from the distance of outer ledge; The length of a, concrete counterweight; ε, partial safety factor for load, value are 1.4.
Secondly, when formal construction, not only to satisfy the requirement of Theoretical Calculation, also should repeatedly try to join, guarantee to move the construction working that can carry out next step under the situation safe against all possibilities.
In addition, power supply for construction inspection.Ensure that power supply for construction is stabilized in 380v, the excessive or too small all standing that all can cause motor causes the unnecessary Psychological Panic of top operating personnel.To check also when power utility check whether earth leakage protective device damages, and will in time change for unsve earth leakage protective device, prevent to get an electric shock and hurt sb.'s feelings.
At last, inspection ground-surface planeness of operation and degree of compaction.When on acclive ground, moving, also should suitably adjust the height of orbit, guarantee the level of job platform, prevent the loading landing.
Make the correct use of little gantry crane by oneself
This homemade small-sized gantry crane device is the mechanical equipment that one was failed, promotes, was installed in transporting something containerized; Not only there is the level transportation to also have vertical transport during normal the operation; Therefore, every small-sized gantry crane device should have fixing personnel to operate when operation, and operating personal must pass through special training; Satisfying under the operating instruction condition of conventional crane, also should satisfy the operating instruction of little gantry crane self:
1, the crash barrier template should prevent its rotation when level is transported, and can carry out the level transportation after waiting to stablize, and prevents to rotate the injury that causes the operating personnel.
What 2, the crash barrier template should make lifting rope and template when removing is affiliated to the degree of tightness appropriateness, just holds the degree of power, and the impact when preventing the template tenesmus causes damage to machinery, avoids unsafe accident generation.
3, small-sized gantry crane device is must 4 liftings by when lifting, prevents that the counterweight junk from hurting sb.'s feelings, and in addition by in the process of lifting by crane, the people that stands and the outage of operating a switch are forbidden in top.
