The utility model discloses a following technical scheme realizes, provides a novel hydraulic support in advance with adjustable it is whole, including two support bodies, every support body all includes the support back timber, and two support back timbers of two support bodies are connected through a plurality of crossbeams of arranging side by side along support back timber major axis direction, are equipped with a plurality of mounting holes of arranging along crossbeam major axis direction on every crossbeam, are equipped with the otic placode of connecting every crossbeam that corresponds respectively on two support back timbers, and every crossbeam all is connected through the otic placode that corresponds on round pin axle and two support back timbers.
Preferably, the two support top beams of the two support bodies are connected through four cross beams which are arranged in parallel along the long axis direction of the support top beams.
Preferably, each cross beam is provided with six mounting holes arranged along the long axis direction of the cross beam, and the six mounting holes are arranged at equal intervals.
Preferably, each beam is a steel beam.
The utility model has the advantages that:
1. the ear plates on the top beam of the support are hinged with the cross beam, so that the left and right support bodies are respectively in different height states, namely the cross beam replaces the top beam of the support to be in contact with the top plate of the roadway, the contact form is changed from line contact to surface contact, on one hand, the top plate of the roadway is prevented from being damaged, on the other hand, the contact surface is increased, and the support stability is improved;
2. the two frame bodies are connected into a whole by the plurality of cross beams, so that the stability and the structural strength of the forepoling are improved;
3. the cross beam is provided with a plurality of mounting holes, the lug plates on the top beam of the bracket are connected with the mounting holes at different positions, so that the center distance between the two bracket bodies can be changed, and the change of the center distance is mainly suitable for the storage requirements of complex roadway conditions or special equipment;

Detailed Description
In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.
As shown in fig. 3-6, the utility model discloses a through two support bodies of transferring a jack 1 to connect, every support body all includes base 2, four-bar linkage 3, two lifting jack 4 and support back timber 5, is prior art to the structure of every support body, and the event is no longer repeated to the structural connection relation that every support body involved. Two support back timber 5 of two support bodies are connected through a plurality of crossbeams 6 that arrange side by side along 5 major axis directions of support back timber, are equipped with a plurality of mounting holes 7 of arranging along 6 major axis directions of crossbeam on every crossbeam 6, are equipped with the otic placode 8 of connecting every crossbeam 6 that corresponds respectively on two support back timber 5, and every crossbeam 6 all is connected with the otic placode 8 that corresponds on two support back timber 5 through round pin axle 9.
Otic placode 8 on support back timber 5 is articulated with crossbeam 6, can realize controlling two support bodies and be in different altitude states respectively, and crossbeam 6 replaces support back timber 5 and the contact of tunnel roof 10 promptly, becomes the face contact with the contact pattern by line contact, has avoided tunnel roof to damage on the one hand, and on the other hand contact surface increases, and support stability improves. The cross beam 6 is provided with a plurality of mounting holes 7, the ear plates 8 on the support top beam 5 are connected with the mounting holes 7 at different positions to change the center distance of the two support bodies, and the change of the center distance mainly adapts to the storage requirements of complex roadway conditions or special equipment.
